How much masking should we use in this ABR case example? We tested a 7-month old baby with a bilateral conductive hearing loss. We wanted to check whether we need to mask or not. The not-masked heari…
Is it possible to measure ABRs via a bone anchored hearing aid? The answer is yes. Bone-anchored hearing system (BAHS) patients are typically those with a conductive (or mixed) or single-sided sensor…
There are a number of things to consider when conducting OAE testing in order to ensure valid and reliable results. Consideration of the factors below will ensure an optimal OAE test. 1. Protocol sel…

I’ve noticed a consistent air bone gap at 4000 Hz during audiometry. Can you explain why this happens? For a complete answer to this issue the reader is strongly urged to read Margolis et al. (2013)…
What is speech audiometry? Speech audiometry, also known as speech testing, employs speech signals to assess if the patient has problems hearing speech or speech in noise. Speech audiometry can be us…

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…
Jack Bennett, International Clinical Trainer at the Interacoustics Academy, describes all the steps you need to take in order to prepare for Real Ear Measurements. This includes how to prepare your e…
In this quick guide, you will learn how to perform the Audible Contrast Threshold (ACT) test. What is the ACT test? The ACT test is an above-threshold, non-language specific test that quantifies a pe…
