Briefly explain how hearing occurs
What will be an ideal response?
The external ear captures sound waves that travel through the external auditory canal to the tympanic membrane. There, the sound waves are converted to mechanical motion as they cause the tympanic membrane to move inward and outward. As it moves, the tympanic membrane moves the malleus, incus, and stapes, which in turn cause the oval window to move. This causes inner ear fluid on the other side of the oval window to begin to vibrate, which is then transmitted throughout the length of the cochlea. In the cochlea, tiny hairs detect different frequencies of sound, sending nerve impulses via the vestibulocochlear nerve to the brain. The brain interprets the nerve impulses as sound.
