In an active cochlea, basilar membranes vibrate more strongly than in a dead cochlea. because all of the outer hair cells slant significantly and alter in length in response to sound. In response to basilar membrane changes, outer hair cells swell and contract. The frequency tuning curve is impacted by damage to the outer hair cells.

<h3>What are the function of Basilar membranes?</h3>

The basilar membrane is the inner ear's primary mechanical component. Over its length, it has graded mass and stiffness characteristics, and its vibration patterns separate incoming sound into its component frequencies, which trigger various cochlear areas.

Impact do outer hair cells have on our hearing :

As a nonlinear amplifier that enables the cochlea to detect sounds with great sensitivity and accuracy, outer hair cells (OHCs) play a crucial role in hearing. These distortion products can be monitored as distortion-product otoacoustic emissions as a result of the nonlinear sound processing (DPOAEs)
