Answer :
How does the basilar membrane respond to different frequencies?
The entire basilar membrane from the base to the apex of the cochlea responds to intense low-frequency sounds, but when threshold is approached, it is most effectively driven by sounds of progressively higher frequencies as one moves from the apex to the base of the cochlea.
The displacement of the basilar membrane therefore provides useful information about the frequency of sound striking the ear by acting like a series of bandpass filters. Each section of the membrane is passed through and therefore responds to all sinusoids with frequencies between two specific values.
The basilar membrane is located in the cochlea. It forms the basis of the organ of Corti, which contains sensory receptors for hearing. Movement of the basilar membrane in response to sound waves causes depolarization of hair cells in the organ of Corti. The hair cells transduce auditory signals into electrical impulses. These impulses are transmitted to the brain where they are interpreted as sound.
Place Theory is a principle of listening to that affirms that, the regions of the basilar membrane are enormously specialized, with every region responding to a specific frequency. Our attention of sound relies upon where every specific frequency produces vibrations along the basilar membrane. By this principle, the pitch of a sound, including a human voice or a musical tone, is detected through the locations where the membrane vibrates, primarily based totally on frequencies similar to the tonotopic arrangement of the auditory neurons.
