What is Tympanic Membrane?
In common parlance, tympanic membrane is the eardrum. It is a thin cone shaped membrane that divides the external ear from the middle ear.
The job of the ear drum or tympanic membrane is to transmit sound from the outer ear to the middle ear. When sound waves hit the ear drum, it vibrates which are then transmitted to the middle ear. The tiny bones of the middle ear then transmit the sounds to the inner ear.
Why is Tympanometry Test needed?
Sometimes this middle ear cavity may gather fluid, thereby impacting your hearing abilities as sound is muffled in the presence of water. A Tympanometry Test tells you if there is fluid in the middle ear.
