Central masking - Oxford Reference
https://www.oxfordreference.com/view/10.1093/oi/authority.20110803095558664
A form of auditory masking in which the test stimulus is presented to one ear and the masking stimulus to the other, the masking being interpreted as central because it cannot be ascribed to any peripheral process occurring in the ear but must arise centrally at or beyond the point where information from the two ears is combined. Also, an analogous form of visual masking usually …
How to Perform Masking in Audiology - eMoyo
https://blog.emoyo.tech/content/masking-in-audiology
When masking the non-test ear, the listening task becomes slightly difficult and results in elevated threshold of the test ear compared to what would have occurred without masking the non-test ear. Known as central masking – this is a side effect of non-test ear masking noise being near-threshold-levels which often creates a 5 dB threshold ...
Central Masking and Neural Activity in the Cochlear ...

A simple theory of central masking is developed on the basis of assumptions that are derived from independent psychophysical and physiological experiments. The theory makes it possible to calculate typical characteristics of single units in the eighth nerve and of certain neural populations of the cochlear nucleus and the medial superior olive.

Central masking It has long been recognized that even with small to moderate amounts of masking noise in the non-test-ear, thresholds of test ear shift by as much as 5- 7 dB. The term central masking is used to explain this phenomenon …

Pure‐tone air conduction thresholds were obtained on 20 normal hearing listeners from 250 to 4000 Hz while white or narrow band noise (centered at the test frequencies) masking was presented to the...
Clinical Masking | Ento Key

Central Masking. As a scientific phenomenon, masking means a threshold shift for a signal that occurs when the noise and signal are presented to the same ear. Very technically, this is called “direct, ipsilateral masking,” and it occurs because the noise and signal are present within the same cochlea.

Answer: There related to the amount of masking it takes to isolate the NTE and TE from responding for each other during air, bone and speech testing. Analogy- Think of goldilocks and the three bears, one is too little, one is too big, and one is just right! Under Masking- …

Figure 4: Masking noise should be louder. Purple indicates that masking is needed but non-feasible (Figure 5). Figure 5: Masking non-feasible. Caveats (1) Be aware that patients need proper instructions before audiometry with masking is undertaken. (2) The switching-on-and-off of the masking noise may be uncomfortable to some patients and cause ...

The aim of this tutorial is to help you understand masking in Audiometry and how to apply the three rules of masking. It also introduces a web-based audiometry simulator tool that might help you to visualise where sounds go and how it all works. ... 40 dB to allow for calibration issues and possible central-masking) then it could be likely that ...
