The eardrum vibrates when sound waves travel into the ear canal and strike it.

Tympanometry-A test where air pressure in the ear canal is varied to test the condition and movement of the eardrum.
Otitis externa refers to an infection of the ear canal (outer ear), the tube leading from the outside opening of the ear in towards the eardrum.
The external ear canal is a tube approximately 1 in (2.5 cm) in length that runs from the outside opening of the ear to the start of the middle ear, which is behind the tympanic membrane (eardrum).
The lining of the ear canal is skin, which is attached directly to the covering of the bone.
Cerumen is designed to protect the ear canal, repel water, and keep the ear canal too acidic to allow bacteria to grow.
Continually exposing the ear canal to moisture may cause significant loss of cerumen.
Without cerumen, the ear canal stops being appropriately acidic, which allows for the growth of microorganisms.

Eardrum-A paper-thin covering stretching across the ear canal that separates the middle and outer ears.
Cerumen impaction refers to the buildup of layers of earwax within the ear canal to the point of blocking the canal and putting pressure on the eardrum.
Cerumen impaction develops when earwax accumulates in the inner part of the ear canal and blocks the eardrum.
It also protects the outer part of the ear canal because it repels water.
The slow movement of the outer layer of skin of the ear canal carries cerumen toward the outer opening of the ear.
Less common causes of cerumen impaction include overproduction of earwax by the glands in the ear canal or an abnormally narrow ear canal that tends to trap the wax.
The way to use these products is to tilt the child's head to one side and fill the ear canal with the eardrops, using an eyedropper.
The diagnosis of impacted cerumen is usually made by examining the ear canal and eardrum with an otoscope, an instrument with a light attached that allows the doctor to look into the canal.
