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…
This tip discusses why you need to be careful when analyzing otoacoustic emissions (OAEs) using the traditional signal-to-noise (SNR) ratio method and which criterion to use instead to improve confid…
Wideband tympanometry (WBT) is an emerging hearing test that is available on the Titan tympanometer, but still lacks adoption. With this resource, we hope to provide some clarity on the test and how…
What are middle-latency responses (MLRs)? Middle-latency responses (MLRs) are related to auditory generators of the subcortical regions Na and Pa components at cortical levels. Na is considered the o…
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…
The Tone in Noise test is a method to identify the comparison of recruitment in the inner ear. When measuring a masked threshold, the sensitivity for level differences increases, making it easier to…
What is the masking level difference (MLD)? The masking level difference (MLD) is the improvement in detecting a tone or speech in noise when the phase of the tone or the noise is reversed by 180 deg…

It is simply a band of noise that is focused is a very narrow band of frequencies, with steep filter slopes, to produce a noise stimulus suitable for threshold estimation. For example, this is a spec…
What is the Rate Study Protocol? The preprogrammed Rate Study test is designed to evaluate the integrity of the auditory nerve and look for retrocochlear lesion abnormalities. Changes in response lat…
