Answer:
The frequency theory of hearing
Explanation:
The frequency theory of hearing contends that the perception of a sound's frequency depends on how often the auditory nerve fires.
The frequency theory of hearing pinpoints that the frequency of the auditory nerve's impulses coincides to the frequency of a tone, which makes it easy to distinguish its pitch. It causes the neural signals speed to go in line with the brain to distinguish the pitch.
Place theory says that the perception of pitch is connected with vibration of certain portions of the basilar membrane, and the frequency theory says the perception of pitch is connected with the frequency at which the whole basilar membrane vibrates.
