Amplitude theory refers to the idea that the height or amplitude of sound waves determines loudness, while place theory suggests that different areas along the basilar membrane of the inner ear respond to different frequencies of sound. Frequency theory proposes that the rate of nerve impulses traveling up the auditory nerve matches the frequency of a tone, but it has difficulty explaining how the nervous system can distinguish pitches that exceed the firing rate of individual neurons. Place theory, on the other hand, can account for higher pitched sounds because it relies on the location of the activated neurons on the basilar membrane, which responds differently to different frequencies of sound waves. Low pitches are best explained by the frequency theory, as the rate of neural firing in response to these frequencies matches the actual frequency of the sound waves. Therefore, pitches in the intermediate range are likely explained by a combination of these two theories.
