The hearing aids can be categorised based on the shape or based on the technology. While the technology required for a patient is ascertained after a rigorous pre-fitting check up and patient's life style profile, the shape is often left to the patient to decide based on their comfort. The following are the models of hearing aids based on the shape
hearing aids are very similar to Completely In the Canal (CIC) hearing aids except that they are slightly smaller and are worn deeper in the ear canal making them completely invisible, even if someone were to peer inside your ear.
Hearing aids fit deeply inside your ear canal, making them almost invisible. The advantages include cosmetic appeal, reduced feedback and excellent sound quality. CICs are suitable for mild to moderately severe hearing losses.
Hearing aids are custom-made to fit almost entirely inside your ear canal, making them very discreet. Many people appreciate the balance of the ITC: small enough to provide some of the same benefits as the CIC, they also provide enough room to accommodate additional options that may not fit on a CIC. ITCs are suitable for mild to moderately severe hearing losses.
hearing aids sit behind the ear and deliver sound directly into the ear. This is because the receiver is located outside of the hearing aid itself and instead inside ear canal. The hearing aid and receiver are connected by a discreet ‘receiver wire’ which houses an electrical cable. It has a more natural and crisper sound quality given the receiver is located inside the ear canal.
Hearing aids sit comfortably behind your ear, allowing amplified sounds to pass through a tube to an earmold that is customized to fit into your ear. Because they are larger, BTEs can generally accommodate bigger batteries for longer life and larger amplifiers for maximum amplification. Most BTEs are compatible with assistive listening devices. BTEs are suitable for mild to profound hearing losses.
