This is a useful aid in interpreting the quality of evoked responses that are seen after gathering and then averaging together a series of epochs in order to cancel the noise. Examples include ABRs…
This video describes the different lateral canal BPPV variants and how to differentiate between them using VNG goggles and the head roll test. You can read the full transcript below. Equipment needed…
The idea of a rotational chair was first introduced by Robert Bárány in 1907 and has been used for a variety of different clinical needs since that time. However, newer vestibular tests, such as the…
Transcript This quick guide video will discuss using otoacoustic emissions as a diagnostic tool and introduce some applications for OAE testing outside of newborn hearing screening. Over recent years…
It is well known that rotational chair testing offers a reliable, repeatable and tolerable stimulus to the inner ear to investigate the function of the vestibular system, specifically the vestibulo-o…
A complete, diagnostic audiological test battery may include: Audiometry Tympanometry Otoacoustic emissions (OAE) Automated auditory brainstem response (ABR) testing Or any combination of the above…
Introduction Free field measurements are really valuable when it comes to understanding your patients hearing function via speech tests or even applying aided testing. However they can be difficult t…
What is Békésy audiometry? Békésy audiometry is an automatic method of measuring audiometric thresholds. It can be used for audiometric screening or in differentiation between the cause of the hearin…

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…
