How do we encode the pitch of a sound? (check all that apply) For low frequency sounds (like a bass), the frequency of action potentials determines the to O Hair cells on the basilar memberate respond to different frequencies. Receptors in the semicircular canal determine pitch. The difference in time between when sound reaches each of the ears determines the tone.
