Binaural squelch

[Stacey]

Hi

Can anyone explain to me in relatively simple terms what binaural squelch is and how it effects audibility? or can they guide me to a referrence that explains it - in simple terms.

I will be eternally grateful

Hey stacey,

Perhaps i know you?? If your the stacey i know, you will recognise me from my name.

Anyway, just to reply to your query about binaural squelch. When signals and noise come from different directions, the brain seperates them by comparing time, intensity and pitch differences between the two ears. The practical effect is that the brain can suppress signals that the listener does not want to hear. For example, in a room with many competing voices, the brain can choose to focus on and listen to one speaker among many.

.. and this is known as binaural squelch

suppose if noise plus signal are presented to both ears at the same time
then the brain can effectively cancel out the noise
this is called binaural squelch
