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…
In cases where you detect a symmetrical hearing loss, traditional audiometry without masking is usually sufficient. However, be aware that in cases of asymmetrical hearing loss, one cannot be certain…

Peter Bray, Ph.D., Interacoustics’ OAE specialist, has more than 35 years' experience when it comes to otoacoustic emissions (OAEs). A good proportion of his career, he has focused on capitalizing on…
It's easy and only takes approximately 2 minutes to perform the Audible Contrast Threshold (ACT) test on Affinity Compact. Learn how to instruct your patient, how to do the actual test and how to use…
What is the tone decay test? The tone decay test can help to identify the adaptation of the auditory system (Carhart, 1957). It involves measuring the perceptual reduction in a continuous tone over t…

Picture this – unfortunately – real-life scenario: You’re using carbon paper or pre-printed templates to transfer a hand-written audiogram to paper. You then hand this off to the patient to bring wit…

The placement of the probe tube is critical when performing real-ear measurements (REMs), as it serves as your point of reference for all the measurements you’ll perform. A poor placement can be detr…
Temporal summation occurs when the human ear integrates energy over time, which stems from a continuous sound. Explanation It is well established in the scientific literature (e.g. Zwislocki in the 1…
