But there are many types of hearing aids that one can choose from depending on their requirements: Body-worn aids: This was the first type of hearing aid introduced to the world, and comprises of a case consisting of electronic amplifier components, controls and battery, and an earmold that comprises of a miniature microphone. While its size is bigger than the modern aids, large amplification, longer battery life and low costs, makes it a desirable choice in emerging countries.

They generally comprise of a case, an earmold and a connection between them. The sound can be received electrically or acoustically by the ear through the BTE aid. People with mild to high hearing disability can use BTEs. This aid can also be classified as Receiver in the Canal/Ear and Earmolds. In–the-ear aids (ITE): These hearing aids are fitted in the outer ear bowl and are customised to fit each individual’s ear. They are mostly used in cases of mild to severe hearing loss, and are smaller in size. ITE are comparatively more expensive than the BTE aids because they are made to order.

CIC ensure comfortable fit because its shell is made-to-order to fit individual ear canal. This type is mostly suitable for children and middle-aged people.
