Hearing aids come in a wide variety of shapes, sizes and models. This consumer's guide consists of consolidated information to assist you in understanding all aspects of hearing aid devices to better make you an informed user and shopper.
Hearing aids today can be grouped under the following categories :
Behind-the-Ear (BTE) – These hearing aids sit behind your ear and are connected to an ear mold placed inside your ear via tubing. BTE devices are fastened on the ear with an ear hook and the ear molds are custom-made to fit the user's ear. BTE hearing aids are known for being robust and durable. They have the ability to produce a lot of power, which accommodates all types of hearing loss.
In the Ear (ITE) – These hearing aids are placed in the ear of the wearer. They are often used by those who suffer moderate hearing loss. Some people who have extremely small ears may not find these models suitable.
In the Canal (ITC) and Completely in the Canal (CIC) – With ITCs and CICs, the whole hearing aid is placed inside the ear canal. ITCs are often larger than CIC devices. CICs are extremely tiny in size and are almost invisible. Some people due to their canal shape or size are unable to wear these types of devices.
Body-Worn Hearing Aids – These hearing aids use an external box worn by the user. The user wears an earpiece, which is attached to the box by a wire. These aids benefit some as they do not block the ear canal, have the ability to use a large battery which supplies the aid with maximum power, and therefore are often recommended for those with severe hearing loss.
