Cochlear AGC attack/releases times?

["Richard H." <auditory@xxxxxxxxxxxxxx>]

Hi,

Does anyone know how the cochlear AGC can be modelled?

Suppose a short tone burst hits the cochlear, how long does it take for the "gain" to be reduced? And then to recover?

Are we talking 1 millisec or 1000 millisecs? [Or 0 millisecs i.e. the transfer function is more like an amplitude compander, without
any time aspect]

And is this AGC very frequency specific - narrow nand, or perhaps critical band?

Or does the cochear not really work like an electronic AGC [or compander] at all?

kind regards,

Richard
