Ear mould
An ear mould is used when you wear a BTE hearing aid. The amplified sound from the hearing aid is sent via tubing to the ear mould, which is inserted into the ear canal.
The ear mould is made using an impression of the user’s ear to ensure that it fits the individual completely.
Eardrum
When sound waves enter the outer ear they travel through the ear canal. At the end of the ear canal the sound waves reach a cone-shaped membrane – the eardrum. When the sound hits the eardrum it vibrates – just like a real drum.
