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…
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)…
Question I read this new article, which is pretty positive about the Eclipse ASSR (Sininger et al 2018). But it raised a question about clinical practice which is not clear to me. Is it necessary to…
IA-AMTAS has eight quality indicators, which can be used to assess the accuracy of the overall result. The first quality indicator refers to accuracy. This looks at the predicted average absolute dif…
In evoked potential testing, there are various ways to measure residual noise. But which one should you use? The fully objective and perhaps easiest method is to use the automated residual noise calc…
This video tutorial provides some tips, tricks, suggestions and ideas for how and when to apply masking noise to the bone conduction ABR. You can read the full transcript below. Introduction This vid…
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…

The aided cortical test can be likened to an evoked potentials method for performing a speech test. This guide will provide a complete introduction to aided cortical testing. Table of contents What i…
As the vestibular diagnostic world continues to expand beyond Videonystagmography (VNG) testing, new tests and features are becoming a necessity to comprehensively and holistically address dizziness…
Objective vestibular assessment provides a valuable insight into the physiological function of the vestibular system. However, vestibular abnormalities will often have vastly different functional imp…
No, the Eclipse does not have a notch (i.e. band-stop) filter. A challenge of these tools is that the line noise is only selectively eliminated with very steep slopes (sharp cut-offs) on either side…
