Frequency theory cannot explain the fact that we can hear frequencies higher than 1,000 Hz because __________
A) the neurons linked to hair cells cannot fire more than 1,000 times per second.
B) the neurons linked to hair cells cannot fire less than 1,000 times per second.
C) different areas of the basilar membrane vibrate at frequencies greater than 1,000 Hz.
D) different areas of the basilar membrane vibrate at frequencies less than 1,000 Hz.

Question

Quizplus · Accepted Answer

Frequency theory proposes that the frequency of a sound wave corresponds to the firing rate of the neurons connected to the hair cells in our ears. However, these neurons can only fire at a maximum rate of around 1,000 times per second. Therefore, frequency theory cannot explain our ability to hear frequencies above 1,000 Hz.
