These outer and middle ears function in the conduction of sound waves through the ear. The inner ear contains structures that receive the auditory waves and relay them to the brain. The auditory or estachian tube is a canal leading which is from middle ear to the pharynx. In an efficient way, this tube can prevent damage to the eardrum and shock to the middle and inner ears. The pressure of air in the middle ear is equal to the pressure of the air in the external environment.
