Hearing aids are highly sophisticated electroacoustic devices that are worn behind the users' ears. These are designed to amplify sounds through having those converted to electrical signals. MD hearing aid comes in different types. Each has specific power and circuitry and among the most popular of these are body worn, behind the ear or BTE, in the ear or ITE, in the canal or ITC and disposal aids. They have distinctive pros and cons; thus, users should only buy in accordance with their audiologists' recommendations or put their auditory system totally at stake otherwise.
Body worn aids are the first to hearing instruments ever invented. These were designed by an American physicist, Harvey Fletcher - the father of stereophonic sound. These devices have a case and an ear mold which are attached by a wire. Their cases are about the size of playing cards. They come with several electronic controls, a battery and amplifier devices.
The BTE is made up of a plastic tube which carries sound through a customized ear mold. This has a bigger size making it pretty easy to manipulate. This can last much longer than a small device. It can be incorporated with a directional microphone. The only odd is, it is never easy to hide particularly if a wearer does not have a long hair.
An in the ear or ITE, on the other hand, is also custom-made with a shell that perfectly fits in the outer part of the ear. It can house a typical volume control as well as directional microphone. It is easy to manipulate and inserted. This tends to be a bit bulky, though.
In the canal or ITC aids are barely noticeable as these are inserted into the opening of the ear canal. These are not priced as much as the ITE but are particularly large enough for the directional microphone. These are also prone to feedback.
Disposable hearing aids are those that have non-replaceable batteries. These are designed for periodic use only or on critical police investigations where wearers only use them during the operation. These are not really ideal for those with inborn hearing disorder. But having these as spare is a good idea.
Ordinary devices that are regulated by the Food and Drug Administration are categorized under Class I. Industrialized countries normally give free aids through healthcare program that are funded by the national government. There are some companies offering heavily discounted devices as well but users are cautioned about purchasing anything if they have yet to have personal conversation with their physicians.
People who have severe conditions are required to pay their audiologists a regular visit. Necessary adjustments for the directional microphone as well as control system are required from time to time. Doing these adjustments without the knowledge and skill can only result in the aids' failure.
An MD hearing aid entails a professional guidance in buying. This is a insensitive device that needs a very careful consideration on several important factors and a series of tests before an individual can purchase one and use.
