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 behind the ear or BTE aid is a plastic tube that carries sound in a customized ear mold. It comes in a larger size making it particularly easy to use. This is believed to last pretty longer than any smaller device. It can be integrated with a directional phone. The odd is, this is not easy to hide unless a wearer has a long hair.
In the ear devices are also custom-made. They have a shell that fits perfectly in the outer ear. They can house typical volume controls and directional microphones. They are also easy to manipulate as well as inserted. They tend to be bulky, though.
An ITC device is barely noticeable as this is inserted right into the ear canal opening. This is not pricey as the ITE. This is large enough to accommodate the directional microphone. It can be pretty prone to feedback, though.
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 with severe condition are required to have a regular consultation with the audiologist. Necessary adjustments are often required particularly on the microphone and control system. Having done those adjustments without the right knowledge and skill will only result in the device's failure.
Buying any MD hearing aid requires a professional guidance from a doctor. The device is very insensitive that necessitates a series of tests as well as a careful consideration on critical factors before a user can get one.
