In the video, you will learn about the core fundamentals of rotational chair testing. We will cover the two most commonly performed tests in the rotational chair: the sinusoidal harmonic acceleration…
This is a pretty interesting question for several reasons but the answers to your question is not easy. The direct answer is we do not know what the rationale is for any advantage of CE-Chirp® over t…
The mono-thermal (“screening”) version of the caloric test refers to stimulating at one temperature on each ear. In many cases the results from two irrigations will be sufficient to inform the tester…
Both are equally valid approaches to hearing aid verification, and historically are associated with the philosophies of prescribing gain according to the well-known NAL (REIG) and DSL (REAR) prescrip…
Jack Bennett, BSc (Hons), International Clinical Trainer from the Interacoustics Academy discusses the physical and environmental factors that effect the quality of measurements achieved when perform…
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…
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…
The regular ABR stimulus is in dB nHL and the masking in dB SPL. How do we know if the levels are comparative? In other words, if the AC toneburst is 40 dB nHL and the masking intensity is 45 dB SPL…
I've watched your MMN webinar. Thank you. Please can you help me evaluate the MMNs below, which are a 1 kHz frequent and 1.5 kHz rare stimulus. Answer Thank you very much for sharing your work. I bel…
This is a pretty interesting question for several reasons but the answers to your question is not easy. The direct answer is we do not know what the rationale is for any advantage of CE-Chirp® over t…
Both of these auditory evoked potentials responses arise from generators in the thalamo-cortical region of the central auditory system and so you would associate them with objectively assessing thres…
Do you have any recommendations for performing diagnostic assessments without a sound booth (Pure Tone Audiometry)? We are assuming you are talking audiometry here (as opposed to areas such as vestib…
