The ear has three chambers: outer, middle and inner ears.Outer ear: pinna/auricle, auditory canal, tympanic membraneMiddle ear: tympanic membrane, ossicles, oval window and auditory tubeInner ear: oval window, cochlea, vestibule, semicircular canals & auditory nerveSound waves travel into the auditory canal and strike the tympanic membrane.The tympanic membrane vibrates.Sound vibrations are amplified and transmitted by the ossicles to the oval window.Vibrations are transferred to fluid environment of the inner ear, converted into electrical energy and sent to the brain for interpretation.
Auditory tube or Eustachian tube connect the middle aer cavity to the pharynx. It helps in regulating the pressure in the middle ear.
