There is more to it than that, the idea that the various hairs are simply
independant discrete detector/integrators is an over simplification.
it is like the (much more closely studied) retina processes, where there is 
local processign (as involved in masking).

THe ear is for example more sensitive to changing pitch, than to changing 
intensity. And, just as a one/F modulation of a visual field is "more
interesting"
than eg a sine modulation, so I expect it would be for the ear.

As anyone with a cat in their studio knows, for only a very small class of
sounds
can make a cat show interest.
