The Hearing Healthcare Pro software will capture audiometry test results, and will allow user input of tympanometry results, physical examination results, and patient history. The software will summarize the inputted data and provide a "normal" or "abnormal" determination. If the decision is "abnormal", the software can make a recommendation for clinical follow-up. The dB Diagnostic Systems, Inc. software is for adult use only and may be used by healthcare providers not normally trained or experienced in hearing, audiology, or otology, such as primary care providers. The Hearing Healthcare Pro software is not intended to make a clinical diagnosis.
The Hearing Healthcare (HHC) Pro is software designed to be used by healthcare providers (HCP) either trained and experienced in hearing, audiology, or otology, such as Ear, Nose, and Throat (ENT) doctors or not, such as primary care providers. The HHC Pro software is not intended to make a clinical diagnosis. The HHC Pro software is a screening product. The software aggregates the inputted data and determines whether the person's hearing is considered normal or abnormal. If the results are abnormal, the software can either provide a recommendation for further clinical consultation with a licensed physician with expertise in Ear, Nose and Throat (ENT), or allow for an ENT-trained physician to enter their own recommendation in a blank text field. Further, the software can distinguish between symmetrical and asymmetrical sensorineural hearing loss; the former would be recommended to see an audiologist or an otolaryngologist who works with an audiogist, the latter would be recommended to an ENT clinical specialist. The HHC Pro software compiles the hearing information previously available to physicians, classifies the data as normal or abnormal with respect to any measureable hearing loss, and identifies the presence of asymmetric hearing results. dB Diagnostics has chosen to validate the algorithm determining the difference between the symmetry and asymmetry of hearing loss as a greater that 20 dB difference between two ears at any test frequency (which are 250, 500, 1000, 2000, 6000, and 8000 Hz). The health care provider uses the HHC Pro to enter hand-held tympanometry results, limited clinical history, and limited physical examination findings, including a Rinne tuning fork test at 512Hz, to further identify patients who would benefit from an ENT evaluation. The HHC Pro device comprises the HHC Pro Software. With the HHC Pro Software, dB Diagnostic Systems distributes the Amplitude T4 audiometer or the OTOpod audiometer, both manufactured by Auditdata A/S and collectively known as a "digital audiometer", a 512Hz Rinne tuning fork, and the Microsoft Surface Pro tablet preloaded with the Microsoft Windows 10 operating system and the HHC Pro Software. An Amplivox Otowave 102 Tympanometer may also be distributed with the HHC Pro software.
The provided text describes a 510(k) submission for the "Hearing Healthcare Pro" software. It focuses on demonstrating substantial equivalence to a predicate device rather than presenting a detailed de novo clinical study with specific acceptance criteria and detailed performance data often found in novel device approvals.
Therefore, much of the requested information regarding acceptance criteria and a study proving the device meets them (especially in the context of typical AI/ML medical device studies with large datasets, expert ground truth, and MRMC studies) is not explicitly available or detailed in this document. The document describes software validation and verification against internal performance specifications and established standards, rather than a clinical performance study with defined acceptance criteria for AI algorithms.
However, based on the information provided, here's what can be extracted and inferred:
1. A table of acceptance criteria and the reported device performance:
The document does not provide a quantitative acceptance criteria table or specific performance metrics like sensitivity, specificity, accuracy, or AUC for an "abnormal" determination or an "asymmetry" detection. Instead, it states:
Criterion | Reported Performance / Validation Method |
---|---|
Software Functionality | "The HHC Pro has been tested and is in compliance with internal software validation bench testing to compare the HHC Pro input test results to the gold standard, Board-Certified Otolaryngologist reviewers for equivalence in the output responses." |
Meeting Design Requirements | "The results of this testing conclude the software has met the design requirements." |
Compliance with Standards | Complies with AAMI / ANSI / ISO 15223-1, ISO 14971, ANSI S3.1-1999 (R2008), FDA Guidance "General Principles of Software Validation," and FDA Guidance "Guidance for the content of Premarket Submission for Software in Medical Devices." |
New Issues of Safety/Effectiveness | "The Hearing Healthcare Pro does not raise new issues of safety or effectiveness and is substantially equivalent to the predicate device." (This is the overarching conclusion of a 510(k) process). |
Algorithm for Asymmetry | Validated algorithm for determining > 20 dB difference between ears at any test frequency (250, 500, 1000, 2000, 6000, 8000 Hz). No quantitative performance metric provided. |
2. Sample size used for the test set and the data provenance:
- Sample Size: Not explicitly stated. The document refers to "software validation bench testing" where "HHC Pro input test results" were compared. This implies a test set, but its size (e.g., number of patient cases, number of data points) is not quantified.
- Data Provenance: Not specified regarding country of origin or whether it was retrospective/prospective clinical data or simulated/bench data. The term "input test results" suggests controlled inputs for testing the software's logic.
3. Number of experts used to establish the ground truth for the test set and the qualifications of those experts:
- Number of Experts: Not specified. It refers to "Board-Certified Otolaryngologist reviewers" (plural, so at least two).
- Qualifications: "Board-Certified Otolaryngologist". No mention of years of experience.
4. Adjudication method for the test set:
- Not explicitly stated. The document mentions "Board-Certified Otolaryngologist reviewers for equivalence in the output responses." This suggests their output was considered the "gold standard," but the method of reconciliation if there were disagreements among reviewers (e.g., 2+1, consensus, majority vote) is not detailed.
5. If a multi-reader multi-case (MRMC) comparative effectiveness study was done, If so, what was the effect size of how much human readers improve with AI vs without AI assistance:
- No, an MRMC comparative effectiveness study was not done or reported. The device is described as "compiling the hearing information previously available to physicians, classifies the data as normal or abnormal with respect to any measureable hearing loss, and identifies the presence of asymmetric hearing results." It's a screening tool that summarizes inputted data and provides a determination/recommendation, not an AI to assist human image interpretation that would typically warrant an MRMC study.
6. If a standalone (i.e., algorithm only without human-in-the-loop performance) was done:
- The study described is essentially a standalone (algorithm only) validation in the sense that the software's classification outputs ("normal"/"abnormal" determination, "asymmetry" detection) were compared to the "gold standard" established by Otolaryngologist reviewers. The "inputs" to the software are measurements and observations (like audiometry results, tympanometry results, physical examination findings, patient history) provided by a human user, meaning it's a computational device processing structured input data to produce an output, rather than interpreting raw medical images or signals directly. The validation appears to focus on the correctness of this processing logic.
7. The type of ground truth used:
- Expert Consensus / Expert Review: The ground truth for the software's output (e.g., "normal" or "abnormal" determination, "asymmetry" identification) was established by "Board-Certified Otolaryngologist reviewers."
8. The sample size for the training set:
- Not applicable / Not specified. This device is presented as a software that processes user-inputted audiometric, tympanometric, and clinical data based on predefined rules (e.g., >20dB difference for asymmetry), rather than a machine learning model that undergoes a distinct "training phase" on a dataset. The document makes no mention of machine learning, neural networks, or deep learning, which would typically involve a training set. It appears to be a rule-based system or an algorithm with pre-defined thresholds.
9. How the ground truth for the training set was established:
- Not applicable. As implied above, there's no mention of a "training set" in the context of machine learning. If the "algorithm" refers to pre-defined rules, those rules would have been established by clinical knowledge and criteria, not by a data-driven training process. The validation described is focused on verifying the correct application of these rules against expert review.

An Amplivox Otowave 102 Tympanometer may also be distributed with the HHC Pro software.
The provided text describes the regulatory filing for the Hearing Healthcare Pro device (K171038). While it mentions performance testing and compliance with standards, it does not provide explicit acceptance criteria or a detailed study report with quantitative performance metrics for the device's determination of "normal" or "abnormal" hearing.
Here's an breakdown based on the information provided, highlighting what is present and what is missing:
1. A table of acceptance criteria and the reported device performance
Missing. The document states that the device "has been tested and is in compliance with internal software validation bench testing to compare the HHC Pro input test results to the gold standard, Board-Certified Otolaryngologist reviewers for equivalence in the output responses." However, it does not provide a table with specific acceptance criteria (e.g., sensitivity, specificity, accuracy thresholds) or the reported numerical performance values.
2. Sample size used for the test set and the data provenance (e.g. country of origin of the data, retrospective or prospective)
Missing. The document refers to "internal software validation bench testing" and comparing "input test results to the gold standard," but does not specify the sample size of these test cases or the provenance of the data used (e.g., number of patient records, country, retrospective/prospective nature).
3. Number of experts used to establish the ground truth for the test set and the qualifications of those experts (e.g., radiologist with 10 years of experience)
The ground truth was established by "Board-Certified Otolaryngologist reviewers." The number of these experts and their specific qualifications (e.g., years of experience) are not specified.
4. Adjudication method (e.g. 2+1, 3+1, none) for the test set
Missing. The document mentions "Board-Certified Otolaryngologist reviewers" establishing the gold standard, but does not describe the adjudication method used if multiple experts were involved (e.g., consensus, majority vote, independent review).
5. If a multi reader multi case (MRMC) comparative effectiveness study was done, If so, what was the effect size of how much human readers improve with AI vs without AI assistance
No. A Multi-Reader Multi-Case (MRMC) comparative effectiveness study was not explicitly mentioned or described.

The touchTymp tympanometer is an electroacoustic test instrument that produces controlled levels of test tones and signals intended for use in conducting diagnostic hearing evaluations and assisting in the diagnosis of possible otologic disorders. It features tympanometry and acoustic reflex audiometry.
The touchTymp is an auditory impedance analyser. The device is intended to change the air pressure in the external auditory canal and measure and graph the mobility characteristics of the tympanic membrane to evaluate the functional condition of the middle ear. The device is used to determine abnormalities in the mobility of the tympanic membrane due to stiffness, flaccidity, or the presence of middle ear pathologies. The device is also used to measure the acoustic reflex threshold which occurs due to contractions of the stapedial muscle following exposure to a strong stimulus. This test allow to assess between central and peripheral pathologies and to identify where the patients uncomfortable loudness level may reside. The instrument is software controlled. The software controls the probe (tone and pressure) stimuli, measures the result and presents the result on a built in display. All functions are set and interpreted by the operator. The technological characteristics are substantially equivalent with predicate device. All technological characteristics are in compliance with the consensus standard ANSI S3.39 for auditory impedance testers.
The provided text details a 510(k) premarket notification for the "touchTymp" device, an auditory impedance tester. The FDA determined the device is substantially equivalent to legally marketed predicate devices.
Here's an analysis of the acceptance criteria and study information provided:
1. Table of Acceptance Criteria and Reported Device Performance
The document does not explicitly state specific quantitative acceptance criteria or a detailed "reported device performance" table in the way one might expect for a study comparing a new algorithm's performance against a gold standard. Instead, it relies on demonstrating compliance with existing standards and substantial equivalence to a predicate device.
The closest we can get to implied "acceptance criteria" and "performance" from this document are:
Acceptance Criteria (Implied from the document) | Reported Device Performance (Implied from the document) |
---|---|
Technological Characteristics Equivalence: The device's technological characteristics must be substantially equivalent to the predicate device. This includes its ability to change air pressure, measure and graph tympanic membrane mobility, evaluate middle ear function, and measure acoustic reflex thresholds. It also implies compliance with the consensus standard ANSI S3.39 for auditory impedance testers. |
Safety and EMC Compliance: The device must comply with current standards for medical device safety and electromagnetic compatibility (EMC).
Performance Equivalence: The device must perform as safely and effectively as the predicate device for its claimed purposes (conducting diagnostic hearing evaluations and assisting in the diagnosis of possible otologic disorders, featuring tympanometry and acoustic reflex audiometry).
Software Control and Interpretation: The software must effectively control probe stimuli, measure results, and present them on a display, with all functions interpretable by the operator. | Technological Characteristics Equivalence: The document explicitly states: "The technological characteristics are substantially equivalent with predicate device. All technological characteristics are in compliance with the consensus standard ANSI S3.39 for auditory impedance testers."
Safety and EMC Compliance: "The device was found in compliance with current standards [for medical device safety and EMC]."
Performance Equivalence: "The verification and validation activities show substantial equivalence with the predicate device and that the modified touchTymp is as safe and effective as the predicate device for its claimed purpose."
Software Control and Interpretation: "The instrument is software controlled. The software controls the probe (tone and pressure) stimuli, measures the result and presents the result on a built in display. All functions are set and interpreted by the operator." |
2. Sample Size Used for the Test Set and Data Provenance
The document states "Clinical tests None applicable" (page 5), indicating that no clinical test set was used for this 510(k) submission. The determination of substantial equivalence was based on nonclinical tests verifying compliance with standards and technological similarity to the predicate device.
3. Number of Experts Used to Establish the Ground Truth for the Test Set and Qualifications
Not applicable, as no clinical test set was used to establish a ground truth.
4. Adjudication Method for the Test Set
Not applicable, as no clinical test set was used.
5. If a Multi Reader Multi Case (MRMC) Comparative Effectiveness Study was done
No. The document explicitly states "Clinical tests None applicable." This type of study would fall under clinical testing.
6. If a Standalone (i.e. algorithm only without human-in-the loop performance) was done
Yes, in a way. The "Nonclinical tests summary" discusses "design verification and validation" performed "according to current standards for medical device safety and EMC and performance of impedance tester." This implies standalone testing of the device's functional performance against engineering specifications and industry standards, without human interpretation as part of a clinical study. However, this is not performance in the sense of an AI algorithm's diagnostic accuracy.
7. The Type of Ground Truth Used
For the nonclinical tests mentioned:
- Compliance with standards: The "ground truth" was the specifications and requirements outlined in standards like ANSI S3.39 for auditory impedance testers, and general medical device safety and EMC standards.
- Equivalence to predicate device: The "ground truth" was the established performance and characteristics of the predicate device (MI 24, K905704).
8. The Sample Size for the Training Set
Not applicable. This device is not an AI/ML algorithm that undergoes a "training set." Its functionality is based on established electroacoustic principles.
9. How the Ground Truth for the Training Set Was Established
Not applicable, as there is no training set for this type of device.

The Interacoustics AT235 Impedance Audiometer is an electroacoustic test instrument that produces controlled levels of test tones and signals intended for use in conducting diagnostic hearing evaluations and assisting in the diagnosis of possible otologic disorders. It features tympanometry, acoustic reflex and air conduction audiometry.
AT235 is an auditory impedance analyser. The device is intended to change the air pressure in the external auditory canal and measure and graph the mobility characteristics of the tympanic membrane to evaluate the functional condition of the middle ear. The device is used to determine abnormalities in the mobility of the tympanic membrane due to stiffness, flaccidity, or the presence of middle ear pathologies. The device is also used to measure the acoustic reflex threshold which occurs due to contractions of the stapedial muscle following exposure to a strong stimulus. This test allow to assess between central and peripheral pathologies and to identify where the patients uncomfortable loudness level may reside. The uncomfortable loudness level is useful when providing rehabilitative amplification methods and determining the correct management process for the patient. The AT235 also includes basic audiometry functions. The instrument is software controlled. The software controls the probe (tone and pressure) stimuli, measures the result and presents the result on a built in display. All functions are set and interpreted by the operator (There are no interpretations of results in the device). The technological characteristics are substantially equivalent with predicate device. All technological characteristics are in compliance with the consensus standard ANSI S3.39 for auditory impedance testers
The provided document is a 510(k) summary for the Interacoustics AT235 Impedance Audiometer. This document focuses on demonstrating substantial equivalence to a predicate device, rather than providing detailed acceptance criteria and a study proving device performance against those criteria in a typical AI/software-as-a-medical-device (SaMD) context.
Therefore, many of the requested points related to acceptance criteria, specific performance metrics, ground truth establishment, training sets, and MRMC studies are not applicable to this type of regulatory submission. The submission relies on demonstrating that the new AT235 maintains the same safety and effectiveness as its previously cleared version (K994254).
Here's a breakdown based on the available information:
1. A table of acceptance criteria and the reported device performance:
This information is not explicitly stated in the document in the format of specific acceptance criteria and performance results (e.g., sensitivity, specificity, accuracy). The document states that the device was found in compliance with current standards and demonstrated substantial equivalence with the predicate device.
The technological characteristics are stated to be in compliance with the consensus standard ANSI S3.39 for auditory impedance testers. This implicitly means the device meets the performance requirements outlined in that standard, but the specific metrics and targets are not detailed in this summary.
2. Sample sized used for the test set and the data provenance:
- Test set sample size: Not applicable. This document refers to device verification and validation activities, not a study involving a test set of patient data with a defined sample size for performance evaluation in the way an AI/SaMD would.
- Data provenance: Not applicable for performance evaluation against a specific test set. The validation activities are described as "following the design control procedure."
3. Number of experts used to establish the ground truth for the test set and the qualifications of those experts:
Not applicable. Ground truth establishment for a patient-level test set is not described as part of this submission. The device is an electroacoustic test instrument; its performance is validated against physical and instrument standards, not typically against expert-labeled patient data in this context.
4. Adjudication method (e.g., 2+1, 3+1, none) for the test set:
Not applicable. There is no mention of an adjudication process for a test set of patient data.
5. If a multi-reader multi-case (MRMC) comparative effectiveness study was done, If so, what was the effect size of how much human readers improve with AI vs without AI assistance:
Not applicable. This device is an audiometer, an electroacoustic test instrument, not an AI-powered diagnostic imaging tool that would typically involve human readers interpreting results.
6. If a standalone (i.e. algorithm only without human-in-the-loop performance) was done:
Not applicable. This device is a measurement instrument. Its "performance" is its ability to accurately measure and present electroacoustic data, not to interpret or diagnose. The document explicitly states: "All functions are set and interpreted by the operator (There are no interpretations of results in the device)."
7. The type of ground truth used (expert consensus, pathology, outcomes data, etc):
The ground truth for this type of device would primarily be instrument calibration standards, physical measurements, and compliance with recognized industry standards (e.g., ANSI S3.39 for auditory impedance testers). The document states: "The device was found in compliance with current standards and demonstrated substantial equivalence with the predicate device."
8. The sample size for the training set:
Not applicable. This device does not use machine learning or AI that requires a training set of data.
9. How the ground truth for the training set was established:
Not applicable. As there is no training set for an AI/ML algorithm, there is no ground truth establishment for such a set.
Summary of what the document does state regarding verification and validation:
The "Nonclinical tests summary" section on page 4-5 clearly states:
- "Following the design control procedure the design verification and validation were performed according to current standards for medical device safety and EMC and performance of impedance tester."
- "The device was found in compliance with current standards and demonstrated substantial equivalence with the predicate device."
- "Clinical tests None applicable"
The "Conclusion" further reiterates:
- "The AT235 as a modification to the predicate device (the previous cleared revision of AT235) uses the same or identical technology and has the same intended use as the predicate device."
- "We trust that the verification and validation activities show substantial equivalence with the predicate device and that the modified AT235 is as safe and effective as the predicate device for its claimed purpose."
In essence, the "study" proving the device meets its acceptance criteria is the comprehensive design verification and validation process against relevant medical device standards (including safety, EMC, and the ANSI S3.39 performance standard) to demonstrate substantial equivalence to its predicate. The specifics of these tests (e.g., specific measurement ranges, accuracy tolerances, etc.) are not detailed in this summary document but would be part of the full 510(k) submission.

The Inventis Middle Ear Analyzers are intended for use on individuals six months of age or older. Flute is a tympanometer. Viola is a combination of audiometer and tympanometer, which reduces the amount of necessary equipment.
Flute is stand-alone tympanometry / reflex diagnostic device. Viola is a stand-alone combined unit, integrating a screening middle ear analyzer and a diagnostic audiometer capable of performing air and bone conduction threshold and speech exams. Flute and Viola are available with or without the integrated thermal printer.
Here's an analysis of the acceptance criteria and supporting study for the Inventis Middle Ear Analyzers, based on the provided 510(k) summary:
The document indicates that the Inventis Middle Ear Analyzers (Flute and Viola) underwent bench testing to demonstrate substantial equivalence to a predicate device, the Interacoustics Audiotraveller, Model AA222 (K022728). The acceptance criteria are largely implicitly defined by compliance with established electrical, mechanical, electromagnetic compatibility, and performance standards for auditory impedance testers and audiometers.
1. Table of Acceptance Criteria and Reported Device Performance:
Acceptance Criteria Category | Specific Standard/Requirement | Reported Device Performance (Inventis Middle Ear Analyzers) |
---|---|---|
Electrical and Mechanical Safety | IEC 60601-1 (Class I, Type B for predicate; Class II, Type BF for new device) | Compliance with IEC 60601-1:2005. "The results demonstrate that the Inventis Middle Ear Analyzer is in compliance with...IEC 60601-1:2005 and is safe as the predicate device." |
Electromagnetic Compatibility (EMC) | IEC 60601-1-2 | Compliance with IEC 60601-1-2:2007. "The results demonstrate that the Inventis Middle Ear Analyzer is in compliance with...IEC 60601-1-2:2007." |
Impedance Measurement Performance | ANSI S3.39 / IEC 60645-5 (Type 2 for both predicate and new device) | "All the necessary performance tests in support of substantial equivalence determination were conducted... The tests demonstrate that the Inventis Middle Ear Analyzer is effective and performs as well as the predicate device." Specific impedance features match, with minor differences: Probe Tone Frequency: 226 Hz, 1kHz (Flute HF); 226 Hz (Viola) vs. 226 Hz, 678 Hz, 800 Hz, 1 kHz (predicate). Compliance Range: up to 8.0 ml (Same as predicate). Pressure Range: -600 to +400 daPa vs. -600 to +300 daPa (predicate). |
Audiometer Performance (Viola only) | ANSI S3.6 / IEC 60645-1 (Type 3 Pure-tone Audiometer for new device; Type 2 Tone Audiometer for predicate) | "All the necessary performance tests in support of substantial equivalence determination were conducted... The tests demonstrate that the Inventis Middle Ear Analyzer is effective and performs as well as the predicate device." Specific audiometry features match, e.g., Available Frequencies, Outputs, Inputs. Note: Viola is a Type 3, predicate was a Type 2. |
Substantial Equivalence to Predicate Device | Overall design, function, safety, technological and performance characteristics, intended use. | "Inventis Middle Ear Analyzers (Flute and Viola) are substantially equivalent to the predicate device with regard to design, function, safety and technological and performance characteristic, intended use. Any differences in the technological characteristics between the devices do not raise any new issues of safety or effectiveness." |
2. Sample Size Used for the Test Set and Data Provenance:
The document describes bench testing, which typically does not involve human subjects or a "test set" in the sense of clinical data. It refers to testing on the device itself against engineering and performance standards. Therefore, specific sample sizes for a "test set" or data provenance (country of origin, retrospective/prospective) are not applicable in the context of this 510(k) submission, as it focuses on demonstrating technical equivalence rather than clinical performance from patient data.
3. Number of Experts Used to Establish Ground Truth for the Test Set and Qualifications:
Not applicable. Ground truth for bench testing is established by the specifications defined in the relevant engineering and performance standards (e.g., ANSI S3.39, IEC 60601-1). There is no "test set" requiring expert adjudication for diagnosis, as would be the case in a clinical study for an AI-powered diagnostic device.
4. Adjudication Method for the Test Set:
Not applicable, as there is no clinical "test set" in this context that would require adjudication.
5. If a Multi-Reader Multi-Case (MRMC) Comparative Effectiveness Study was done:
No. An MRMC comparative effectiveness study was not done. This 510(k) submission is for a traditional medical device (auditory impedance tester and audiometer), not an AI-assisted diagnostic tool.
6. If a Standalone (algorithm only without human-in-the-loop performance) was done:
Not applicable. The device described is a medical instrument for conducting diagnostic evaluations, not an algorithm, and its performance is inherently mechanical/electronic, not based on an independent algorithm's output.
7. The type of ground truth used:

The Titan Impedance System is an electroacoustic test instrument that produces controlled levels of test tones and signals intended for use in conduction diagnostic hearing evaluations and assisting in the diagnosis of possible otologic disorders. It features tympanometry and acoustic reflexes.
The Titan Impedance System measures various acoustic properties of the ear, namely power reflectance, power absorption, transmittance, reflectance group delay, complex acoustic impedance and admittance, and equivalent ear canal volume. These measures allow the evaluation of the functional condition of the middle and outer ear.
The Titan Impedance System is suitable for all populations including new-born infants.
The Titan Impedance System is to be used by trained personnel only such as audiologists, ENT surgeons, doctors, hearing healthcare professionals or personnel with a similar level of education. The device should not be used without the necessary knowledge and training to understand its use and how results should be interpreted.
The instrument is audiometric equipment used for measuring aural acoustic impedance and admittance (According to ANSI S3.39).
The Titan is a platform with multi functions depending of licensing. The license function for this submission is IMP440 (IMP) for measurement of aural acoustic impedance and admittance.
The Titan IMP test is intended to change the air pressure in the external auditory canal and measure and graph the mobility characteristics of the tympanic membrane to evaluate the functional condition of the middle ear. The IMP test function is already cleared by FDA 510(k) premarket notification K083861 (04/09/2009)
The instrument is a diagnostic/clinical instrument (as defined in IEC60645-5), but provides normative data for guidance.
Titan consists of a handheld unit named Titan, Titan Cradle (cleared by FDA 510(k) premarket notification K083861) and PC software (Titan Suite/IMP440). The measurements are controlled by the handheld unit.
A connection box (shoulder box) enables different types of accessories to be connected to the platform
The Titan platform can connect to PC software via a Bluetooth connection.
The Interacoustics Titan IMP440 WBT is an electroacoustic test instrument intended for diagnostic hearing evaluations and assisting in the diagnosis of otologic disorders. It measures various acoustic properties of the ear, including power reflectance, power absorption, transmittance, reflectance group delay, complex acoustic impedance and admittance, and equivalent ear canal volume.
Here's an analysis of the acceptance criteria and the study proving the device meets them, based on the provided text:
1. Table of Acceptance Criteria and Reported Device Performance
The provided 510(k) summary focuses on demonstrating substantial equivalence to predicate devices rather than detailing specific numeric acceptance criteria for performance metrics. The comparison table (on pages 3-5 of the original document) primarily highlights similarities and differences in technical characteristics and functionalities between the Titan IMP440 WBT and its predicate devices (Titan with IMP440 and MIMOSA HEARID).
Implicit Acceptance Criteria (based on substantial equivalence):
Feature/Measure | Acceptance Criteria (Substantial Equivalence) | Reported Device Performance (Titan IMP440 WBT) |
---|---|---|
Indications for Use | "Same" as predicate devices (Titan IMP440 and MIMOSA HEARID): Conduct diagnostic hearing evaluations, assist in diagnosing otologic disorders, perform tympanometry and acoustic reflexes, measure various acoustic properties of the ear (power reflectance, absorption, transmittance, delay, impedance, admittance, ear canal volume). | Meets: Identical intended use as the previous Titan IMP440, with additional paragraphs matching the predicate MIMOSA HEARID regarding specific acoustic property measurements, suitability for all populations (including newborns), and use by trained personnel. |
Target Population | "Same" as predicate devices: All populations, including newborn infants. | Meets: Suitable for all populations, including newborn infants. |
Intended User | "Same" as predicate devices: Trained personnel (audiologists, ENT surgeons, doctors, hearing healthcare professionals). | Meets: To be used by trained personnel only. |
Safety Standard | Compliance with IEC 60601-1 (assumed for predicate). | Meets: Complies with IEC 60601-1. |
EMC Standard | Compliance with IEC 60601-1-2 (assumed for predicate). | Meets: Complies with IEC 60601-1-2. |
Performance Standard | Unknown for MIMOSA HEARID, but expectation of compliance with state-of-the-art standards. | Meets: Complies with IEC 60645-5 / ANSI S3.39 (Type 1 Diagnostic/Clinical). |
Frequency Range | Functionally equivalent to 200-6000 Hz of MIMOSA HEARID, ensuring no negative impact on safety or effectiveness. | Meets (Substantially Equivalent): 250-8000 Hz. Justified that expanded range (due to better transducers) does not influence safety or effectiveness. |
Intensity Range | Functionally equivalent to 0-80 dB SPL of MIMOSA HEARID, ensuring no negative impact on safety or effectiveness. | Meets (Substantially Equivalent): 90/94 dB peSPL = 70/74 dB SPL (fixed). Justified that fixed range is within predicate device's variable range and does not impact safety/effectiveness for WBT (wideband tympanometry) as pure tone stimulation is not relevant. |
Stimuli | Functionally equivalent to Chirp/Pure Tone of MIMOSA HEARID. | Meets (Substantially Equivalent): Chirp (Frequency linearized click). Pure Tone is not relevant for this WBT function. |
Artefact Rejection | Presence of an artefact rejection system. | Meets (Substantially Equivalent): Present, described as removing responses contaminated with noise or noise artifacts, similar to the predicate's equivalent system. |
Normative Data | Presence of normative data. | Meets (Substantially Equivalent): Present, used to indicate normal middle ear function in the user interface. Based on referenced studies [1, 2]. |
Reflectance Area Index | Presence of a system for enhanced diagnosis via reflectance area index. | Meets (Substantially Equivalent): Uses shaded area (10/90 or 5/95 percentiles) indicating normative region. Identical functionality to normative data display. |
Measurement Protocols | Customizable measurement protocols. | Meets: Users can change the sequence of measurements to fit diagnostic and clinical purposes. |
Customizable Display Parameters | Customizable display of graphs/parameters. | Meets (Substantially Equivalent): Users can change how many graphs are presented, with the intended purpose being the same as the predicate. |
Otitis Media Examples | Presence of examples for Otitis Media with Effusion. | Meets (Substantially Equivalent): Sketched examples of curve characteristics based on measurements [4]. |
Measures (Power Reflectance, Absorption, Transmittance, Acoustic Impedance, Resistance, Reactance, Admittance, Conductance, Susceptance, Equivalent Volume) | Presence of these specific acoustic measurements as defined by ANSI S3.39. | Meets (Substantially Equivalent): All listed measures are present, often explicitly stated as equivalent or directly derived from each other (e.g., reflectance to absorbance), and align with ANSI S3.39 definitions of these quantities. Power absorbance is plotted, noting its identity to power transmittance. |
2. Sample Size Used for the Test Set and Data Provenance
The document explicitly states: "No clinical tests were performed" (page 9) for the Titan IMP440 WBT device in this 510(k) submission. Therefore, there is no test set sample size mentioned, nor any data provenance (country of origin, retrospective/prospective). The assessment relies on compliance with international standards and comparison to predicate devices' performance.
3. Number of Experts Used to Establish the Ground Truth for the Test Set and Their Qualifications
Given that no clinical tests were performed, no experts were used to establish ground truth for a test set as part of this specific submission.
4. Adjudication Method for the Test Set
Since no clinical tests and no test set were used, there was no adjudication method applied for this submission.
5. Multi-Reader, Multi-Case (MRMC) Comparative Effectiveness Study
No MRMC comparative effectiveness study was done. The submission solely focuses on demonstrating substantial equivalence through technical comparisons and compliance with standards, not on human reader performance improvement with or without AI assistance.
6. Standalone (Algorithm Only) Performance Study
No standalone (algorithm only) performance study was conducted that would typically involve a test set. Instead, the device's functional performance was verified through compliance with recognized standards (IEC 60645-5 / ANSI S3.39) and comparison against the technical specifications of predicate devices.
7. Type of Ground Truth Used
For the newly submitted device, no direct ground truth (e.g., pathology, outcomes data) was established for its own performance. The grounds for acceptance criteria are:
- Compliance with international standards: IEC 60601-1, IEC 60601-1-2, IEC 60645-5 / ANSI S3.39.
- Substantial equivalence to predicate devices: The functionality and performance characteristics of the Titan IMP440 WBT were compared to the cleared Titan IMP440 and MIMOSA HEARID. The assumption is that if it is substantially equivalent and meets standards, it is safe and effective.
The normative data included in the device (mentioned as "present" in the comparison table) are based on published research [1, 2], which would inherently have involved clinical studies to establish their "ground truth" (e.g., healthy ear function). However, this is for the normative data itself, not for a direct performance study of the Titan IMP440 WBT in this submission.
8. Sample Size for the Training Set
As the device described is a medical instrument for measurement and diagnosis (not an AI algorithm that "learns" from data in a conventional sense), the concept of a "training set" is not applicable in the way it is for machine learning algorithms. The device's functionality is engineered based on established acoustic principles and standards. The "normative data" could be considered analogous to a statistical reference for interpretation rather than a training set for an algorithm. However, the sample sizes for the studies used to generate these normative data [1, 2] are not provided in this excerpt, though they would have been part of the original research.
9. How the Ground Truth for the Training Set Was Established
Again, the concept of a "training set ground truth" is not directly applicable. If considering the normative data as an analogous reference, its "ground truth" would have been established through the research studies it was based on (e.g., "adults with normal hearing" [1], and "newborn infants" [2]). These studies would have involved clinical assessments to define "normal" (or the specific conditions being studied). However, the details of these ground truth establishments are beyond the scope of this 510(k) summary, referring instead to external academic publications.

The Titan Impedance System is an electroacoustic test instrument that produces controlled levels of test tones and signals intended for use in conduction diagnostic hearing evaluations and assisting in the diagnosis of possible otologic disorders. It features tympanometry and acoustics reflex.
Titan IMP440 consists of a handheld unit named Titan, Titan Cradle and PC software (Titan Suite and Titan IMP440 module). The measurements are controlled by the handheld unit. Titan IMP440 is going to be offered as 3 configurations that will support screening, diagnostic and clinic users. A license system makes it possible within each configuration to select which functionality the user wants to be incorporated in the system. Titan IMP440 is an impedance product based on a hardware platform named Titan Platform. It uses a cabinet named Titan but may use any other cabinets as long as it meets the requirement of the platform. Other products will in the future be developed to the Titan platform and submitted as required and thereby become a part of the Titan System Family as Titan IMP440. A connection box named Titan Shoulder Box enables different types of accessories to the hardware platform.
The provided text is a 510(k) summary for the Interacoustics Titan IMP440 device, which is an auditory impedance tester. This type of document is a premarket notification to the FDA to demonstrate substantial equivalence to a legally marketed predicate device. As such, it focuses on comparing the new device's technological characteristics and performance to an existing, cleared device, rather than conducting a full clinical study with acceptance criteria, sample sizes, and expert validation in the way a novel AI/ML device might.
Therefore, many of the requested categories (e.g., sample size for training/test sets, number of experts for ground truth, adjudication methods, MRMC studies, standalone performance, specific acceptance criteria with reported performance, ground truth types) are NOT applicable to this type of regulatory submission as it appears from the provided text.
Based on the information given, here's what can be extracted:
1. A table of acceptance criteria and the reported device performance
The document states: "The performance data indicated that the Titan Impedance System meets all specified requirements, and is substantially equivalent to the predicate device." However, the specific acceptance criteria (e.g., accuracy thresholds, precision ranges) are not detailed in this summary. The "specified requirements" likely refer to internal design specifications and relevant industry standards for auditory impedance testers, but these are not enumerated here.
Acceptance Criteria | Reported Device Performance |
---|---|
Not specified in this document. | "meets all specified requirements" and "is substantially equivalent to the predicate device." |
2. Sample size used for the test set and the data provenance
Not applicable. This 510(k) summary does not describe a clinical study with a specific test set, sample size, or data provenance in the context of an AI/ML device. The "performance data" likely refers to engineering tests and comparisons against the predicate device's specifications.
3. Number of experts used to establish the ground truth for the test set and the qualifications of those experts
Not applicable. This is not a clinical study involving expert-established ground truth for a test set.
4. Adjudication method for the test set
Not applicable.
5. If a multi reader multi case (MRMC) comparative effectiveness study was done, If so, what was the effect size of how much human readers improve with AI vs without AI assistance
Not applicable. The Titan IMP440 is an electroacoustic test instrument, not an AI-assisted diagnostic tool that would involve human readers interpreting results with or without AI assistance.
6. If a standalone (i.e. algorithm only without human-in-the-loop performance) was done
Not applicable. The device is a diagnostic instrument, not an algorithm, and its performance is inherently standalone in generating measurement data for a clinician to interpret.
7. The type of ground truth used
Not applicable in the typical sense of a clinical study or AI/ML validation. For an impedance system, "ground truth" would be the physically accurate measurement of the auditory system's impedance. The document implies that the device's measurements are accurate enough to be considered substantially equivalent to the predicate device, which is already an accepted method for obtaining such "ground truth" in routine clinical use.
8. The sample size for the training set
Not applicable. This device does not use machine learning, so there is no training set.
9. How the ground truth for the training set was established
Not applicable.

The Amplivox Otowave is designed for use by trained operators in hospitals, ENT clinics, and audiologist offices for the detection of possible otologic disorders associated with the functioning of the middle ear. The instrument performs two types of measurement: Tympanometry is used to measure the compliance of the tympanic membrane and middle ear at a fixed frequency over a range of pressures. Reflex tests are used to measure stapedial reflexes. The Otowave measures ipsilateral reflexes and, when selected, reflex measurement is automatically carried out after a tympanogram is taken.
This is a hand held portable tympanometer. It features: Automatic measurement of ear canal volume, tympanic compliance peak, placement . of the peak and the gradient. . Automatic detection of stapedial reflexes. . Up to 30, dual-ear patient tests can be stored in non-volatile memory. 9 . Configurable settings for user preferences, held in non-volatile memory. . Printout via an infrared link to a thermal printer. . Transfer to Windows XP via an infrared IrDA link for storage and display using . NOAH..
The Amplivox Otowave 102 Hand Held Portable Tympanometer (K081841) was cleared based on substantial equivalence to predicate devices, rather than meeting specific performance acceptance criteria from a clinical study. The provided document does not contain an acceptance criteria table or a detailed study demonstrating device performance against such criteria.
Instead, the submission focuses on the device's intended use, description, and comparison to legally marketed predicate devices (K925585, GSI 38 AUTO TYMP LUCAS GRASON-STADLER, INC. and K060885 the Maico MI 44 Tympanometer) to establish substantial equivalence.
Here's a breakdown of the requested information based on the provided text:
1. A table of acceptance criteria and the reported device performance
This information is not provided in the given document. The submission states: "The results of bench, user, and standards testing indicates that the new device is as safe and effective as the predicate devices." However, it does not detail specific acceptance criteria or quantitative performance metrics from these tests.
2. Sample sized used for the test set and the data provenance
This information is not provided in the given document. The document mentions "bench, user, and standards testing" but does not specify sample sizes or data provenance (e.g., country of origin, retrospective/prospective nature).
3. Number of experts used to establish the ground truth for the test set and the qualifications of those experts
This information is not provided in the given document. The clearance relies on substantial equivalence, not on the establishment of ground truth by experts for a specific test set.
4. Adjudication method for the test set
This information is not provided in the given document.
5. If a multi reader multi case (MRMC) comparative effectiveness study was done, If so, what was the effect size of how much human readers improve with AI vs without AI assistance
A Multi-Reader Multi-Case (MRMC) comparative effectiveness study was not mentioned or indicated in the provided document. The device is a diagnostic instrument, not an AI-assisted diagnostic tool for human readers; therefore, this type of study would not be applicable or expected in this context.
6. If a standalone (i.e. algorithm only without human-in-the loop performance) was done
The device is a standalone tympanometer. Its performance would inherently be "algorithm only" as it provides automated measurements. However, no specific study detailing its standalone performance with quantitative results is provided. The comparison is made against predicate devices, implying similar performance characteristics.
7. The type of ground truth used
This information is not explicitly stated in the provided document. Given that the device performs measurements for the "detection of possible otologic disorders," the implied 'ground truth' in a clinical setting would likely be established through clinical diagnosis by medical professionals (e.g., ENT specialists, audiologists) or potentially through pathology/imaging in more severe cases. However, no specific ground truth method for the pre-market testing is described.
8. The sample size for the training set
This information is not provided in the given document. The device is a traditional medical instrument, not an AI/machine learning system, so the concept of a "training set" in that context does not apply.
9. How the ground truth for the training set was established
This information is not provided in the given document, as it is not an AI/machine learning device requiring a training set with established ground truth.
Summary of what is available from the document regarding acceptance criteria and study:
The submission for the Amplivox Otowave 102 Hand Held Portable Tympanometer (K081841) focuses on demonstrating substantial equivalence to existing predicate devices (K925585, GSI 38 AUTO TYMP LUCAS GRASON-STADLER, INC. and K060885 the Maico MI 44 Tympanometer).
The evidence for this substantial equivalence is primarily based on:
- Intended Use Compatibility: The intended use of the Otowave 102 is highly similar to that of the predicate devices.
- Technological Characteristics: The device performs similar measurements (Tympanometry and Reflex tests) as the predicate devices. Differences noted are primarily in form factor (handheld vs. desktop) and power source (battery-operated vs. AC).
- Safety and Effectiveness Claims: The document states, "The results of bench, user, and standards testing indicates that the new device is as safe and effective as the predicate devices." However, no detailed reports, specific results, or quantitative acceptance criteria from these tests are provided. The "standards testing" refers to adherence to safety standards like UL and IEC 60601-1, which would involve meeting predefined benchmarks for electrical and mechanical safety.
In essence, the "acceptance criteria" here are implicitly met by demonstrating that the new device is comparable in function, safety, and effectiveness to devices already cleared for market. The study, if one could call it that, is a comparative assessment against predicate devices supported by general "bench, user, and standards testing" without specific details on methodologies or results in the provided document.
