    Intended Use

    The HyperSound Group Auditory Trainer is indicated for use as a group auditory trainer or group hearing aid used to communicate simultaneously with one or more listeners with or without hearing loss and with or without the use of hearing aids in order to improve clarity and comprehension of sounds generated from sources such as a microphone, CD/DVD player, TV, Stereo System or other sound generation systems.

    Device Description

    The HyperSound Audio System (HSS) utilizes a specially designed emitter (speaker) that delivers beamlike sound that is clear to the listener. The beamed audio content begins to demodulate in the air within six inches of the emitter and results in a cone-like transmission of sound waves that can be directed towards the listener. This device is intended for sale as an over-the-counter product and can be used with any sound source and at any distance from 3 feet to 50 feet or more from the emitters (speakers). Ultrasonic technology has been used for many years in industry and is also utilized in medical devices, such as ultrasonic nebulizers. The ultrasonic sound waves this product is based upon have also used in commercial and localized communications, and they are below the ultrasonic sound safety limits established by OSHA as required by OSHA Noise Standard, 29 CFR 1910.95. The device consists of an amplifier, software, and an emitter (speaker). No ear plugs or head phones are required to use this device. The device is distant from and does not touch the intended patient/user.

    AI/ML Overview

    Here's a summary of the acceptance criteria and the study proving the device meets them, based on the provided text:

    Acceptance Criteria and Device Performance

    Acceptance Criteria (Benchmarking / Equivalence Standard)Reported Device Performance (HyperSound Audio System)
    ANSI S3.2-2009 Modified Rhyme Test (MRT) scoreMean score of 91%
    Speech understanding improvement for hearing-impaired subjects (compared to conventional speakers at 70 dB)Median AZBio scores increased from 0.0% to 34.9% (quiet), and from 1.8% to 51.6% (noise). Median CNC whole word test scores increased from 0.0% to 54.0%. Median phoneme test scores from 4.0% to 63.4%. (All with p=0.008 or p=0.004)

    Note: The document focuses on demonstrating substantial equivalence rather than defining explicit acceptance criteria in a quantitative pass/fail manner. The reported performance metrics are used to support this claim of equivalence and clinical effectiveness.

    Study Details

    1. Sample size used for the test set and the data provenance:

      • Sample Size: 10 adult patients with mild to severe hearing loss.
      • Data Provenance: Clinical study conducted at the California Hearing and Balance Center in La Jolla, CA (USA). Prospective data from a controlled audiology laboratory.
    2. Number of experts used to establish the ground truth for the test set and the qualifications of those experts:

      • The document does not explicitly state the number or qualifications of experts establishing ground truth for the test set. However, a "controlled audiology laboratory" suggests that audiologists or similarly qualified professionals would have conducted and interpreted the speech tests.
    3. Adjudication method (e.g., 2+1, 3+1, none) for the test set:

      • Not specified. The study was a "single-blinded, randomized cross over clinical study," but no details on expert adjudication of results are provided beyond standard audiology testing procedures.
    4. 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. This device is not an AI-assisted diagnostic tool, but rather an auditory trainer. Therefore, an MRMC study comparing human reader performance with and without AI assistance is not applicable. The clinical study does compare the HSS system to conventional speakers, showing a significant improvement in speech understanding with the HSS.
    5. If a standalone (i.e. algorithm only without human-in-the-loop performance) was done:

      • Yes, for the non-clinical testing, "Equivalency testing to a predicate device was performed by an independent laboratory pursuant to ANSI S3.2-2009," which would be a standalone assessment of the device's audio output characteristics.
      • The clinical study assessed the device's performance directly with human users, but it's not an "algorithm only" test as the device itself is a physical auditory system.
    6. The type of ground truth used (expert consensus, pathology, outcomes data, etc.):

      • The ground truth for the clinical study was established by standardized audiological speech tests: Modified Rhyme Test (MRT), Consonant-Nucleus-Consonant (CNC) in quiet, and AzBio in noise. These are objective measures of speech understanding, which serve as the "ground truth" for evaluating the hearing device's effectiveness.
    7. The sample size for the training set:

      • This device is not an AI/ML model that requires a "training set." It is an auditory trainer employing ultrasonic technology. The design and performance are based on engineering principles and verified through bench testing and clinical studies, not machine learning training.
    8. How the ground truth for the training set was established:

      • Not applicable, as there is no training set for this type of device.

    Intended Use

    The Model PE 600 Series devices form the Impaired Group Amplification System which is used by adults and children in public halls, theaters, churches, courtrooms and other public gatherings and provide auditory assistance to hearing impaired persons.

    Device Description

    The Model PE 600 Series consists of:

    1. The Model PE 600E is a power amplifier which is combined with an infrared LED array. Audio signals from a sound system are processed and broadcast into the listening area by means of infrared light.
    2. The Model PE 600R is a body worn infrared receiver. It receives the infrared light signals from the PE 600E and converts these signals to high level audio signals required by the hearing impaired listener. The audio signals can be adjusted to meet the user.
    3. The PE 601R is an Infrared Headset Receiver. It receives the infrared light signals from the PE 600E and converts these signals to audio signals required by the hearing impaired listener. This devise is capable of stereo reception so that different audio signals can be received simultaneously and fed to each ear separately.
    4. The PE 602R is an Infrared Headset Receiver. It receives the infrared light signals from the PE 600E and converts these signals to audio signals required by the hearing impaired listener. The device is capable of receiving infrared light signals transmitted on two separate frequencies. A switch on the headset allows the user to select the program frequency desired. The selected program is heard in each ear.
    AI/ML Overview

    The provided text is a 510(k) summary for the Phonic Ear Model PE600 Series Infrared Group Amplification System. This device is an auditory assistance system for hearing-impaired individuals in various public settings.

    Here's an analysis of the provided text in relation to your request:

    Elimination of interference from electrical circuits/lighting."The use of the higher 2.3 Mhz and 2.8 Mhz transmission frequencies eliminates the interference which may be caused by electrical circuits and lighting, thus providing a clearer, interference free sound to the listener."
    Flexible mounting options for emitter."The ability of the PE600E Infrared Emitter to be mounted in several ways provide more flexibility for use as either a small portable system or in permanently installed systems for large auditoriums."
    Scalability for large installations."The ability of the systems to be enlarged by the addition of more infrared emitters provides full sound coverage even in very large installations."
    Compatibility with tele-coils in hearing aids."The ability of the infrared receivers to power the tele-coil found in most hearing aids enables the users to utilize their own hearing aids which provide more convenience of use as well as allowing the user to hear the same sounds they would normally hear using only their hearing aid."
    No dead spots or sound fade-outs."The design of the infrared detecting elements in the receivers allow the user to sit anywhere within the infrared environment without experiencing the dead spots or sound fade-outs usually found in most installations."
    Increased speech understanding and word discrimination."The use of an Infrared Group Amplification System provides increased speech understanding and word discrimination for the hearing impaired in listening environments such as school classrooms, concert halls, theaters or other similar situations where noises, reverberation or poor acoustical treatment may be found. The use of these systems also reduce the detrimental effects caused by the distance between the speaker or sound source and the hearing impaired listener."
    Dual-channel operation for language translation."The ability of the infrared system to operate on two channels simultaneously allows the system to be used for language translation thus integrating users of different languages into the same environment."
    Adaptability for secure sound environments."The PE600 Infrared Systems are especially adaptable for use in installations where security of the sound is desired, such as in court rooms or jury deliberation rooms."

    2. Sample Size Used for the Test Set and Data Provenance

    The provided 510(k) summary does not detail a specific test set, its sample size, or its data provenance (e.g., country of origin, retrospective/prospective). The document primarily cites clinical studies on FM Auditory Training Systems to substantiate the effectiveness claims related to increased speech understanding and word discrimination. It does not describe a new clinical trial specifically for the PE600 Series.

    3. Number of Experts Used to Establish Ground Truth for the Test Set and Qualifications of Those Experts

    This information is not provided in the document. The substantiation for effectiveness claims references "many clinical studies" by specific researchers (Dr. David Hawkins, Dr. Mark Ross, Robert Benoit, M.A., and Dr. Thomas Giolas) but does not outline how ground truth was established within those studies or if they were done for the PE600 series directly.

    4. Adjudication Method for the Test Set

    This information is not provided in the 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

    This section is not applicable to the Phonic Ear Model PE600 Series Infrared Group Amplification System. This device is a sound amplification system, not an AI-assisted diagnostic or interpretive tool that would involve "human readers" or AI assistance in the way typically seen in medical imaging or diagnostic studies.

    6. If a Standalone (i.e., algorithm only without human-in-the-loop performance) was done

    This section is not applicable as the device is not an algorithm, but a hardware-based amplification system.

    7. The Type of Ground Truth Used

    For the claims related to "increased speech understanding and word discrimination," the document states: "Effectiveness claims outlined in paragraph 16 have been NOTE: substantiated by the results of many clinical studies made over the years since the introduction of FM Auditory Training Systems. Three such study reports by Dr. David Hawkins, Dr. Mark Ross, Robert Benoit, M.A. and Dr. Thomas Giolas form a part of this 510(k) submission."

    This indicates that the ground truth for effectiveness was established through prior clinical studies (outcomes data) on similar FM Auditory Training Systems, rather than a new, specific ground truth established for the PE600 series in this submission. The nature of these "clinical studies" would likely involve objective measures of speech recognition or discrimination in controlled listening environments.

    8. The Sample Size for the Training Set

    This information is not provided as this device does not involve a "training set" in the context of machine learning or AI models.

    9. How the Ground Truth for the Training Set was Established

    This information is not provided as it is not applicable to the type of device being described.


    Summary of Limitations in the Provided Document for Your Request:

    The document is a 510(k) summary from 1997 for an infrared group amplification system. Its purpose is to demonstrate substantial equivalence to predicate devices, not to present a detailed clinical study with quantifiable acceptance criteria, specific test/training sets, or AI performance metrics. Therefore, much of the information you requested (especially around sample sizes, expert qualifications, adjudication, MRMC studies, and AI-specific ground truth) is not present in this type of regulatory submission. The "study that proves the device meets the acceptance criteria" is broadly defined as prior clinical research on similar FM Auditory Training Systems, used to support the general effectiveness claims.

    AI/ML Overview

    The provided document is a 510(k) notification for a medical device (Group Auditory Trainer, Model PE571R). It describes the safety and effectiveness of the device, but it does not contain the specific acceptance criteria or a study designed to prove the device meets these criteria in the typical sense of a clinical trial with predefined metrics.

    Instead, the document focuses on demonstrating substantial equivalence to previously approved devices, a requirement for 510(k) submissions. The "effectiveness" section lists various features and functionalities of the device and how they contribute to its intended use. For these effectiveness claims, the document refers to existing clinical studies that support the general concept of FM Auditory Training Systems, rather than a single study specifically designed for this particular device model and its acceptance criteria.

    Therefore, many of the requested information points cannot be directly extracted from this document in the way they would be from a clinical trial report.

    Here's a breakdown of what can and cannot be answered based on the provided text:

    1. A table of acceptance criteria and the reported device performance

    • Acceptance Criteria: Not explicitly defined in terms of measurable performance metrics with thresholds (e.g., "sensitivity must be >X%"). The criteria for acceptance are implicitly that the device is safe and effective, and substantially equivalent to predicate devices.
    • Reported Device Performance: The document describes various features and functionalities as contributing to the device's effectiveness. These are qualitative descriptions of performance rather than quantitative measurements against specific criteria. For example, "The maximum power output of the receiver can be set to the appropriate level required by the user and then locked at that level to prevent over amplification..." describes a safety/effectiveness feature without providing a specific quantitative performance value or an acceptance threshold for that value.
    Acceptance Criteria (Implicit from Effectiveness Claims)Reported Device Performance (as described)
    Prevention of over-amplification/painMaximum power output can be set and locked.
    Proper balance between signal sourcesIndependent control of receiver microphones and FM transmitter signal levels.
    Indication of battery statusCHG/LOW BATT LED provides positive indication of charge and low battery.
    Indication of FM signal receptionNO FM LED indicates when no FM signal is received.
    Easy visibility of FM frequency channelEnlarging lens on front face.
    Multiple operating modes3-position switch for various operating modes.
    Attenuation of audio signals for emphasis7-position FM level switch for each ear.
    Limiting output to appropriate sound pressure level7-position SSPL switch for each ear.
    Adjustable amplification level7-position GAIN switch for each ear.
    Adjustable frequency response7-position TONE switch for each ear.
    Options for microphone input2-position microphone switch for built-in or BTE device microphone.
    Compact size and light weightUse of solid state surface mount components and integrated circuits.
    Natural sound in different environmentsUse of several optional listening accessories.
    Wide choice of fitting possibilitiesAbility to use a variety of listening accessories.
    Optimum performance in most listening environmentsSelection of operating modes (FM only, FM+mic, mic only).
    Easy change of FM channels2 rotary switches under a latching cover.
    Improved word discrimination in noisy environments, reduced effects of distance/reverberation"Effectiveness claims outlined in paragraph 17 have been substantiated by the results of many clinical studies made over the years since the introduction of FM Auditory Training Systems." (General claim, not device-specific study)

    2. Sample sized used for the test set and the data provenance (e.g. country of origin of the data, retrospective or prospective)

    • Not applicable for this document. The safety and effectiveness claims are based on substantial equivalence to predicate devices and general understanding of FM Auditory Training Systems, supported by existing literature. There is no specific "test set" for this particular device's performance in a clinical study detailed here. The technical specifications were obtained by testing devices per ANSI Standard ANSI.S3.22-1987, which is a standard for hearing aid characteristics, not a clinical test set in the usual sense.

    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)

    • Not applicable. No specific test set with ground truth established by experts for this device is detailed in the submission. The acceptance of the device relies on its technical specifications meeting standards and its features aligning with established principles of FM auditory trainers, as judged by the FDA.

    4. Adjudication method (e.g. 2+1, 3+1, none) for the test set

    • Not applicable. No specific test set requiring adjudication is 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

    • Not applicable. This device is an auditory trainer, not an AI-powered diagnostic tool for interpretation by human readers. It's designed to assist hearing, not assist interpretation.

    6. If a standalone (i.e. algorithm only without human-in-the-loop performance) was done

    • Not applicable. This is a hardware device with specific audio processing capabilities, not an algorithm in the sense of AI. Its "performance" is its ability to transmit and amplify sound according to its design, which is tested against engineering standards (like ANSI S3.22-1987).

    7. The type of ground truth used (expert consensus, pathology, outcomes data, etc)

    • For the claims of improved word discrimination, reduced effects of distance/reverberation (paragraph 17), the document references "many clinical studies made over the years since the introduction of FM Auditory Training Systems." It specifically mentions "Three such study reports by Dr. David Hawkins, Dr. Mark Ross, Robert Benoit, M.A. and Dr. Thomas Giolas form a part of this 510K submission." These studies would likely use outcomes data (e.g., speech recognition scores in various conditions) as their ground truth for demonstrating the effectiveness of FM systems in general. However, the details of how ground truth was established in those specific studies are not provided in this document.
    • For the technical specifications, the "ground truth" is adherence to the ANSI Standard ANSI.S3.22-1987, which defines objective measurement methods for hearing aid characteristics.

    8. The sample size for the training set

    • Not applicable. This is not an AI/machine learning device that would require a training set.

    9. How the ground truth for the training set was established

    • Not applicable.

    In summary, this 510(k) notification primarily relies on demonstrating that the device's design, features, and technical specifications are substantially equivalent to legally marketed predicate devices and adhere to relevant engineering standards. The effectiveness claims for FM auditory trainers in general are supported by existing clinical literature, rather than a new, dedicated clinical study specifically for this model with defined acceptance criteria and a test set.
