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…

“Eclipse eABR is a valuable tool in the evaluation of the threshold and functional status of the auditory system,” says Prof. Martin Walger, from the Cochlear Implant Center of the ENT University Cli…
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 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…
Temporal summation occurs when the human ear integrates energy over time, which stems from a continuous sound. Explanation It is well established in the scientific literature (e.g. Zwislocki in the 1…
