Experiments support this notion of two pitch perception mechanisms.
- a sort of counting mechanism (lower frequencies)
- another mechanism that takes over when the ear cannot ``count''
peaks in the signal's time envelope.
It is plausible that the high-frequency mechanisms relies on the
amplitude of excitation along the basilar membrane.
Mechanisms appear to be equally effective at about 640
Hz.
