Ears and Hearing. The ear is a group of sensory organs in the head that collaborate to produce the sense of hearing. Together these organs perform the amazing function of converting sound waves in air into electrical signals to transmit to the brain. The ear also contains several special structures that produce the bodyâs sense of equilibrium, or balance. Three major regions make up the ear: the outer ear, middle ear, and inner ear.
The function of membranes and levers in the ear is to transmit  sound efficiently from air to fluid. The auditory receptors of the  inner ear operate in a fluid environment, â¦ and that it is really an  underwater sound receiver.
