Behind-the-Ear (BTE) Hearing Aids: The BTE device’s components are contained in a small protective plastic case that can be placed behind the ear. With the help of clear tubing, this plastic casing is attached to an earphone. Because it can fit many types of earpieces, this type of hearing aid is primarily favored by young people. With a child’s growth, the earpieces must be replaced.
On-the-ear or mini BTE aids: This kind of gadget is small and fits behind or on the ear. This device is attached to a small, invisible tube. Mini BTEs allow decreased occlusion to penetrate the ear canal, improving comfort and addressing cosmetic problems.
On-the-ear or micro BTE aids: This kind of gadget is small and fits behind or on the ear. This device is attached to a small, invisible tube. Mini BTEs allow decreased occlusion to penetrate the ear canal, improving comfort and addressing cosmetic problems.
In-the-ear aids (ITE): The majority of an in-the-ear aid’s (ITE) components are housed in a shell that sits on the ear’s exterior surface. These devices are larger than in-the-canal and completely-in-the-canal aids.
In-the-canal (ITC) aids and completely-in-the-canal (CIC) aids: This type of hearing aid has a small casing that fits partially or entirely into the ear canal. When compared to other types of hearing aids, they are the tiniest.
Features of Hearing Aids
The hearing devices possess various features that assist a person in different types of communication situations. The components present in the hearing aid are as follows:
Directional microphone: The microphone receives the sound waves from the person’s surrounding environment and converts them into electrical signals. It amplifies the sound coming from a specific direction as compared to sound coming from other directions.
Amplifier: The function of the amplifier is to increase the loudness of the signals received from the microphone. There are computerized components that modify the sounds because the relevant sound can be amplified.
Receiver: The receiver is also known as the speaker. The purpose of the receiver is to convert the electrical signals of the microphone into acoustic signals. An individual hears these acoustic signals.
Battery: The power source of the hearing aid is provided by the battery. A hearing aid needs the power to operate.
