The cochlea as a graded bank of independent, simultaneously excited resonators: calculated properties of an apparent 'travelling wave'

Bell, James Andrew


There have been two main theories of how the cochlea works: resonance and travelling wave. The first says the cochlea comprises a bank of tiny resonating elements, like piano strings, which respond directly to sound pressure (the excitation is in parallel to the elements). The second considers that differential pressure across the basilar membrane causes a hydrodynamically coupled wave to propagate, like a ripple on a pond, from base to apex (i.e., the excitation is in series). Yet a bank...[Show more]
