OAE made clinical

Otoacoustic emissions (OAEs) are not just an essential clinical tool in newborn hearing screening, but also in clinical audiology. OAEs are sounds that are generated in the cochlea in response to external stimuli. These emissions can be evoked and measured, providing vital information of cochlea function.

Why use OAE as a diagnostic tool?

OAEs can be utilized to investigate types and causes of hearing loss. OAEs can be analyzed over a wider range of frequencies and thereby enable a more extensive look at cochlea function. Clinical OAE is particularly beneficial for patients suffering from tinnitus or ototoxic-induced hearing loss or patients exposed to occupational noise.

We have gathered everything you need to know about OAE in an extensive guide.

Ototoxicity monitoring

One application for diagnostic otoacoustic emissions is in the use of ototoxicity monitoring. Monitoring protocols aim to assist in the identification of ototoxicity which can then inform dose changes, adjustments to treatment plans, and early rehabilitation to mitigate the effects of ototoxicity. Of the evoked family of otoacoustic emissions, distortion product OAEs (DPOAEs) lend themselves better to ototoxicity monitoring than transient evoked OAEs (TEOAEs).

Pressurized OAE

The first tympanometers in the 1950s were not able to compensate for negative middle ear pressure. This is no longer the case. Today, compensating for a negative middle ear pressure is the clinical standard in all tympanometers. Imagine if this was the case with your OAE device? Interacoustics’ pressurized OAE compensates for the shift in peak compliance, allowing you to perform pressurized DPOAE and TEOAE despite of negative middle ear pressure.

In fact, studies show a remarkable improvement in the amplitude of pressurized OAE at frequencies below 2 kHz. Particularly children with negative ear pressure can obtain a full and reliable measurement even though they may have small amounts of fluid in their ear.

Optimizing OAE detection

Interacoustics has several experts within OAE. In a constant effort to improve testing methods and to secure reliable test results, our experts are deeply engaged with advanced engineering and complex algorithms.

One of our experts is Peter Bray, a pioneer in newborn screening and clinical OAE.

„Interacoustics’ clinical OAE products incorporate years and years of advancements in terms of evolutionary OAE technology. OAE is the only test that actually tests the efficacy of the outer hair cells within the cochlea. It therefore forms an essential part of hearing healthcare professionals’ test battery.“
