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…
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…
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…
I want to ask a question about the article from Ferm et al., 2013 titled: “Comparison of ABR response amplitude, test time, and estimation of hearing threshold using frequency specific chirp and tone…
It’s difficult to answer the question about how close you can get to threshold using eABR. eABR testing allows us to record a threshold on the equipment, and this is then used to set the T level on t…
For caloric testing, I am just thinking if we can do cold or warm water alone, why we need to do bithermal beside the benefit of better averaging. Answer: Well your question already encapsulates one…

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…
This video provides an overview of the advantages and the disadvantages of using distortion product OAE (DPOAE) or transient evoked OAE (TEOAE) assessments. You can read the full transcript below. DP…
This video guides clinicians on the selection of a protocol and parameters to record the ocular VEMP. Transcript Darren Whelan: I'd like just to take a moment to have a look at the oVEMP parameters…

This video demontrates a live recording of the ocular VEMP, and the identification of the biphasic response, and the marking of the waveform. Transcript Darren Whelan: Now that we have our patient pr…
