Different Types Of Hearing Aids
Hearing aids have evolved over the years in terms of their varied uses and efficiency. Although the basic job of any hearing aid is to ensure that the sound came be amplified enough to help distinguish, there are a number of different ways in which it is done. This will again depend on the types of hearing aid you are using, which can be categorized as follows.
Normally hearing aids vary in size, power, and the circuit.
Body worn aids: A wire, attached to the hearing aid, powered by a case which can be carried about. The case consists of all the amplifier components, battery, controls, and more. A very simple to use and cheap, which provide a long battery life and better sound quality through enhanced amplification.
Behind-the-ear aids: This type is more useful for people, who suffer from sever hearing loss. The amplification is better when compared to body worn aids and is easier to handle also. They are a bit more on the expensive side, but is a good investment for the features and ease of use this hearing aid boasts.
In-the-ear aids: Body worn and behind the ear are both effective for sound amplification. But a better alternative would be in-the-ear hearing aids, which provide an even greater quality of amplification. Modern circuits in the hearing aid service a better control and feedback regulation and loud noise cancellation. Feedback is a loud squealing or whistling caused due to sudden sound change, which is controlled by these hearing aids.
In-the-ear canal hearing aids: In-the-ear-canal hearing aids are specially designed to be inserted deep into the ear canal, which is the not visible even at close proximity. The chances of occlusion and compression effect are also minimized in this model since the ear shell is designed to not block any natural sound escaping as a result of talking or simple activities like chewing.
Over-the-ear hearing aids: These are slightly different from behind-the-ear hearing aids since they are more smartly designed and compact to make a comfortable fit behind the ear. The hearing aid is primarily deigned to reduce occlusion effect.
