The place theory and the frequency theory both explain how the human ear perceives different frequencies of sound. According to the place theory, different frequencies are detected in different locations within the cochlea. The frequency theory, on the other hand, suggests that the entire basilar membrane vibrates in response to sound waves, and the frequency of the sound is determined by the rate at which the hair cells send signals to the brain. Together, these theories help to explain how a wide range of frequencies is heard by the ear.
