Behind the ear Hearing Aid The ear mold connects a BTE instrument to the ear and is individually shaped for each wearer. It is important because it fulfills multiple functions for acoustics and better hearing. One of the most important tasks of the ear mold is to conduct the amplified sound to the eardrum.
