The description focuses on standard signal processing and data averaging techniques for OAE measurement, with no mention of AI or ML algorithms for analysis or interpretation.
No
The device is used for diagnosis and screening of hearing disorders, not for treatment.
Yes
The device explicitly states in its intended use that it "can provide diagnostic information" and is "indicated for use by trained health care professionals (audiologists, physicians) to further assess cochlear function for the purpose of diagnosis and treatment of hearing disorders."
No
The device description explicitly states that the AuDX system, with which the AuDX I/O software is used, is a "combination of hardware and software" and includes components like miniature receivers, a miniature microphone, and a Bio-logic OAE probe. The software is an "option" to be used "in conjunction with" the hardware system.
Based on the provided text, this device is not an IVD (In Vitro Diagnostic).
Here's why:
- IVD Definition: In Vitro Diagnostics are tests performed on samples taken from the human body, such as blood, urine, or tissue, to detect diseases, conditions, or infections.
- Device Function: The AuDX Otoacoustic Emissions Measurement System works by producing and measuring acoustic signals within the ear canal. It does not analyze biological samples taken from the body.
- Intended Use: The intended use is to assess cochlear function and screen for hearing disorders by measuring physiological responses (otoacoustic emissions) within the ear.
Therefore, the device operates in vivo (within the living body) rather than in vitro (in glass/outside the body).

Intended Use / Indications for Use
The 'AuDX Otoacoustic Emissions Measurement System with AuDX 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.
The AuDX Otoacoustic Emissions Measurement System produces controlled acoustic signals in the ear canal and measures the resulting evoked otoacoustic emissions (OAEs) that are generated by the inner ear as a result of normal peripheral hearing processes. The AuDX device performs both transient evoked otoacoustic emissions (TEOAE) and distortion product otoacoustic emissions (DPOAE) tests that can be utilized in hearing screening and diagnostic test environments. The AuDX I/O is a software option intended to provide accurate online information and to be used in conjunction with the AuDX system. The AuDX I/O software enables the AuDX device user to perform DPOAE testing at annular frequencies and at the same intensity levels. The graphical representation of the test results in the form of stimulus level presented versus measured DPOAE level at each tested frequency provides an effective way for the user to view and evaluate stimulus level-sensitive information about DPOAE responses.
As an OAE based screening tool, AuDX is indicated for use by any personnel (nurses, technicians, volunteers) who are trained to operate its interface for the purpose of performing an objective, automated physiologic screening measure with a Pass/Refer result requiring no further clinical interpretation. Additionally, as a tool that can provide critical information, the device is indicated for use by trained health care professionals (audiologists, physicians) to further assess cochlear function for the purpose of diagnosis and treatment of hearing disorders and by obtaining the DPOAE I/O functions.

Device Description
The AuDX I/O Function is a Windows® based software application for use with the AuDX Otoacoustic Emissions Measurement System. The AuDX I/O software enables the AuDX device user to perform DPOAE testing at different 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.
The AuDX Otoacoustic Emissions Measurement System performs transient evoked otoacoustic emissions (TEOAE) and distortion product otoacoustic emissions (DPOAE) tests. Using a combination of hardware and software, the AuDX system produces a controlled acoustic signal in the ear canal and measures the resulting evoked emissions that are qenerated by the inner ear as a result of normal hearing process. The stimuli are presented 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 and averages data samples until specified measurement 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 user defined custom protocols or default test protocols and measured OAE test parameters.
The AuDX I/O is a software option to be used in conjunction with the AuDX 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 AuDX I/O software option enables the AuDX 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.
