Answer:
Place.
Explanation:
Place theory explains the different perception of sounds on the basis of the different sound waves. This theory helps to explain how the individual can differentiate different pitch sounds.
The different sound frequency causes vibration at the basilar membrane of the cochlea. The different areas of cochlear membrane gets activated by the different frequency of sound. These different vibration enable to distinguish between high pitch and low pitch sounds.
Thus, the answer is place theory.
