The document describes standard signal processing and automated algorithms (like POVR) for analyzing auditory responses, but does not mention AI or ML.
No
The device is described as a diagnostic tool used to measure or determine cochlear function and screen for hearing, not to treat a condition.
Yes
The device is indicated to "measure or determine cochlear function" and to perform "DPOAE Input/Output (I/O) testing". It also provides a "Pass/Refer recommendation" or calculates and presents "DP and noise floor amplitudes", all of which are diagnostic functions.
No
The device description clearly states that the ABaer system, with which the software option is used, includes hardware components such as electrodes, acoustic transducers (insert earphones, headphones, OAE probe, acoustic ear couplers), miniature receivers, and a miniature microphone. The software is an option for this hardware-dependent system.
Based on the provided text, this device is not an In Vitro Diagnostic (IVD).
Here's why:
- IVDs analyze samples taken from the human body. The description of the ABaer System clearly states that it measures responses within the ear canal and electrical activity on the head. It does not analyze biological samples like blood, urine, or tissue.
- The device measures physiological responses. The ABaer System measures auditory evoked responses (electrical activity from the nervous system) and otoacoustic emissions (sounds generated by the inner ear). These are physiological measurements, not analyses of in vitro samples.
The device is a diagnostic tool used to assess hearing function by interacting directly with the patient's body, not by analyzing samples taken from the body.

Intended Use / Indications for Use
The Hearing Screening System (HSS) ABaer performs an automated brainstem auditory evoked response (ABaer) screening and/or an automated otoacoustic emissions (AOAE) screening. The automated auditory brainstem response test (AABR) involves placement of three recording electrodes on an infant's head. The electrodes record the electrical activity generated by the auditory nervous system that result from presentation of a click stimulus into the ear. The automated otoacoustic emissions (AOAE) screening involves producing controlled acoustic signals in the ear canal and measuring the resulting evoked otoacoustic emissions that are generated by the inner ear as a result of normal hearing processes. The ABaer device performs both distortion product otoacoustic emissions (DPOAE) tests and transient evoked otoacoustic emissions (TEOAE) tests.
The ABaer I/O is a software option to be used in conjunction with the ABaer System. The standard DPOAE test measures otoacoustic response to a series of frequency-pairs of tones, varying the frequency while keeping the level or intensity of the stimulus tones at a constant level. The ABaer I/O software option enables the ABaer device user to perform DPOAE testing at different stimulus intensities in order to obtain the 'DPOAE Input / Output (!/O) function' for user defined test frequencies, frequency. ratios and intensity levels. The graphical representation of the test results in the form of stimulus level presented versus measured DPOAE level provides an effective way for the user to view and evaluate stimulus level-sensitive information about DPOAE responses. DPOAE threshold is the lowest stimulus intensity level which produces DPOAE response amplitude that is distinguishable from the level of system distortion and from the noise floor. DPOAE threshold is expressed in much of the published literature as the lowest intensity of the F2 stimulus that generates a clear DPOAE response. DPOAE threshold does not equate to and should not be confused with audiometric and auditory threshold. Whereas auditory threshold measures assess the integrity of the entire auditory system from outer ear to cortex, DPOAE threshold measures, which the user can interpret from the DPOAE I/O functions, are limited to assessment of outer hair cell function in the cochlea only.
The 'ABaer System with ABaer I/O Function' is indicated for use when it is necessary for a trained health care professional to measure or determine cochlear function. The device can be used for patients of all ages, from newborn infants through adults, to include geriatric patients. The otoacoustic emissions test is especially indicated for use in testing individuals for whom behavioral results are deemed unreliable, such as infants, young children, and cognitively impaired adults.

Device Description
The ABaer I/O Function is a Windows® based software application for use with the ABaer Hearing Screening System. The ABaer I/O software option enables the ABaer device user to perform DPOAE Input/Output (I/O) testing at different test frequencies, frequency ratios and intensity levels in addition to the ABR and OAE based hearing screening functions. The graphical representation of the test results in the form of stimulus level presented versus measured DPOAE level provides an effective way for the user to view and evaluate stimulus level-sensitive information about DPOAE responses.
The ABaer Hearing Screening System (HSS) performs an automated auditory evoked response (ABaer) screening and/or an automated otoacoustic emissions (AOAE) screening. The automated auditory brainstem response test (ABaer) involves placement of three recording electrodes on an infant's head. The electrodes record electrical activity generated by the auditory nervous system that results from the presentation of a click stimulus into the patient's ear via acoustic transducers (i.e. insert earphones, headphones, OAE probe, acoustic ear couplers). The system collects and averages evoked potential data in order to perform ABR based screening, recording and analysis functions, provides one channel of data recording, and includes the Point Optimized Variance Ratio (POVR) algorithm for optimizing signal quality, implementing the automated screening function and enhancing speed of test completion in the same manner as in the predicate device (K021801). The device presents the resulting POVR score and a Pass/Refer recommendation to the user.
The automated otoacoustic emissions (AOAE) screening functionality of the ABaer system involves producing controlled acoustic signals in the ear canal and measures the resulting evoked otoacoustic emissions that are generated by the inner ear as a result of normal hearing processes. The ABaer device performs both distortion product otoacoustic emissions (DPOAE) tests and transient evoked otoacoustic emissions (TEOAE) tests.
The OAE stimuli are generated via miniature receivers and the sounds in the external ear canal are recorded via a miniature microphone, all embedded in the Bio-logic OAE probe. The system collects, averages and analyzes data samples until specified measurement and test parameters are achieved. For transient evoked otoacoustic emissions (TEOAEs), the reproducibility and the difference value between the TEOAE and the noise floor amplitudes are calculated and presented to the user. For distortion product otoacoustic emissions (DPOAEs), the DP and noise floor amplitudes are calculated and presented to the user. A pass or refer recommendation is assigned at the end of the test automatically based on the test protocol parameters and measured OAE parameters.
The ABaer I/O is a software option to be used in conjunction with the ABaer system. The standard DPOAE test measures otoacoustic response to a series of frequency-pairs of tones, varving the frequency while keeping the level or intensity of the stimulus tones at a constant level. The ABaer I/O software option enables the ABaer device user to perform DPOAE testing at different stimulus intensities in order to obtain the 'DPOAE Input / Output (I/O) function' for user defined test frequencies, frequency ratios and intensity levels. The graphical representation of the test results in the form of stimulus level vs. DPOAE level provides an effective way for the user to view and evaluate stimulus level-sensitive information about DPOAE response.
