Auditory masking
Auditory Masking
Auditory masking is a phenomenon that occurs when the perception of one sound is affected by the presence of another sound. This can happen when the two sounds are presented simultaneously, or when one sound is presented immediately before or after the other.
Pronunciation
Auditory masking is pronounced as /ˈɔːdɪtəri ˈmæskɪŋ/.
Etymology
The term "auditory masking" is derived from the English words "auditory", meaning related to the sense of hearing, and "masking", meaning to conceal or obscure.
Types of Auditory Masking
There are two main types of auditory masking: Simultaneous masking and Temporal masking.
Simultaneous masking occurs when a sound is masked by another sound that is present at the same time.
Temporal masking can be of two types: Preceding masking (also known as backward masking), where a sound is masked by a subsequent sound, and Following masking (also known as forward masking), where a sound is masked by a preceding sound.
