The basilar membrane and the hair cells of the cochlea function as a sharply tuned frequency analyzer. Sound is transmitted to the inner ear via vibration of the tympanic membrane, leading to movement of the middle ear bones (malleus, incus, and stapes). Movement of the stapes on the oval window generates a pressure wave in the perilymph within the cochlea, causing the basilar membrane to vibrate. Sounds of different frequencies vibrate different parts of the basilar memb… WebCochlear microphonics represent the early components of the acoustic brainstem responses, occur in the 0.7–1 ms window poststimulus, and show similar waveform characteristics to the stimulus. They are a far-field reflection of auditory activity of the eighth nerve in response to an acoustic stimulus.
