Otoacoustic emissions (OAEs) are sounds that are generated by movement of the outer hair cells in a healthy functioning cochlea in response to external stimuli.
Essential tool for differential diagnosis
OAEs are not a test of hearing, and cannot estimate the type or degree of hearing loss as can be achieved with pure tone audiometry or auditory steady-state response (ASSR) testing. But they are an essential tool in both newborn hearing screening and diagnostic audiology for the differential diagnosis of hearing conditions.
Screening and diagnostic OAE
The application of OAEs in screening is very different to that when used for diagnostic purposes. It is extremely important to select the correct test settings or protocol, depending on the patient or expected use of the test results.
Our new OAE guide gives you a thorough introduction to OAE measurements and analysis. It guides you in your selection of the most appropriate test protocol and in your analysis of your test results.
