hearing

the sense by which sounds are perceived, by conversion of sound waves into nerves impulses, which are then interpreted by the brain. Also, the capacity to perceive sound. The organ of hearing is the ear, which is divided into three sections, the outer, middle and inner ear. Each plays a special role in hearing. Connecting the middle ear with the nasopharynx is the pharyngotympanic canal, through which air enters to equalize the pressure on both sides of the tympanic membrane (eardrum).
