These numbers represent the number of cycles in a puretone burst sound signal commonly used in Auditory Brainstem Response (ABR) testing for hearing threshold estimation. The ABR relies upon an abrup…
This video shows you how to perform a sound field analysis before Aided Cortical testing. We recommend that you perform a new sound field analysis for each patient. It only takes a moment. You can re…
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…
Air-bone gaps are the difference in sensitivity threshold between air and bone conduction transducers. This measurement helps distinguish between conductive and sensorineural hearing losses, as well…
The Carhart notch is a notch in a bone conduction audiogram of more than 2 kHz, and was first described by Raymond Carhart, Ph.D., in 1950. Explanation Stimulation of the ear via bone conducted vibra…
The Interacoustics Academy welcomed Torben Poulsen, Professor Emeritus, from the Department of Electrical Engineering at the Technical University of Denmark to deliver a lecture on the topic of speec…
We are excited to share the faces of our 9 new colleagues who have recently joined the great Interacoustics team. Meet them below. Emilie Nielsen Emilie is a recent graduate of English Studies from t…

When we think about the causes of vertigo and disequilibrium in children, it can be useful to separate this population into those with, and those without, hearing loss. For those children without hea…
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 negative middle ear pressure is the clinical sta…
