This statement is true. Frequency theory and place theory are the two main theories that explain how we perceive the pitch of a sound. Frequency theory suggests that the basilar membrane in the inner ear vibrates at the same frequency as the sound wave, and this frequency is transmitted to the brain to create the perception of pitch. Place theory, on the other hand, suggests that different frequencies of sound are processed in different locations along the basilar membrane, and the brain interprets the location of these signals to perceive pitch.
