What is the acoustic reflex? The acoustic reflex is the contraction of the stapedius muscle elicited by the presentation of an acoustically loud sound. When either ear is presented with a loud sound…

In evoked potential testing, there are various ways to measure residual noise. But which one should you use? The fully objective and perhaps easiest method is to use the automated residual noise calc…
What are distortion product otoacoustic emissions (DPOAEs)? Distortion Product Otoacoustic Emissions (DPOAEs) are acoustic signals that can be detected in the ear canal of a person with normal outer…
What is the mismatch negativity (MMN) response? The mismatch negativity (MMN) response is a negative wave elicited in an ‘oddball’ paradigm where by a deviant stimuli is presented amongst a stream of…

Screening protocols It is possible to create a screening protocol in the TEOAE module that provides a test outcome labelled as PASS, REFER or INCOMPLETE. The application of TEOAEs in screening is ver…

An important consideration when it comes to performing aided cortical testing is around the stimuli used for the test. Limitations of previous aided cortical stimuli There were concerns regarding som…
One application for diagnostic otoacoustic emissions is in the use of ototoxicity monitoring. Ototoxic agents include antibiotics (particularly aminoglycosides), loop diuretics such as furosemide, ch…
