According to the ________________ theory, the perception of pitch is related to the frequency at which the basilar membrane vibrates
A) frequency
B) opponent process
C) place
D) volley
Answer: A
Rationale: According to frequency theory the perception of pitch is related to the frequency at which the basilar membrane vibrates. A 70 Hz sound, at 70 cycles per second, stimulates the hair cells 70 times per second. Thus, 70 nerve impulses per second travel from the auditory nerves to the brain, which interprets the sound frequency in terms of pitch.
