Behind the ear, also referred to as BTE, hearing aids are far and away the most widely used kind of hearing aid. These hearing aids are also what many people photograph when hearing aids are described. The technology which make a BTE hearing aid function are housed in a situation which fits behind the ear and has a tube that connects it to an mold which fits in the ear canal.

They're built to support the whole spectral range of hearing losses, from the mild to the significant. While they're more conspicuous then hearing aids that fit completely in the ear canal, they've a number of benefits that attract a broad selection of hearing impaired people. Additionally, BTE hearing aids can be found in numerous shapes, sizes and colors. So some behind the head models are not as conspicuous then the others.

Because behind the ear hearing aids are larger then their entirely in the channel, or CIC, counterparts, they can more easily house a greater rev and stronger battery and consequently may be particularly beneficial to individuals with a severe hearing loss. BTE hearing aids may also be rather flexible because they come in the absolute most traditional analog style as well as in the recently popularized digitally powered style of hearing aids.

When financial constraints are an issue, behind the ear units certainly win out over hearing aids which fit completely in the ear canal. For their larger size, other groups of people to whom BTE hearing aids have more appeal then CIC models are the elderly, arthritis patients and others with related problems and fine motor control disabilities.

Finally since CIC models necessitate the wearing of a heavier system in the canal then only the light ear mold attached to BTE hearing aids, there is commonly less ear canal discomfort with the former.

In the late 1800s the first commercially manufactured hearing aids were branded and became available to the general public. The first behind the ear hearing aids got on the scene over fifty years ago. compare audiology

Prior to this, hearing aids were generally amplifiers used somewhere on your body and these were large and expensive, due partly to rapid battery consumption. With the development of the smaller junction transistor in 1952, widespread BTE hearing aid use became more of a real possibility.

Due to improvements in the technology of circuitry,1964 found another boom in use of BTE units and the use of human anatomy used hearing aids dropped to less then twenty percent. By 1972 prototypes for hearing aids which may be set to many different listening conditions, were being created. These 20 years showed continued improvements and improvements in hearing aid technology.

Size controls were included with many behind the ear units in the 1990s and digital hearing aids started appearing in the mid nineties. There's been extended new arrivals in the hearing aid world ever since then such as for example remanufactured hearing aids, disposable hearing aids and over-the-counter hearing aids. Who knows what the continuing future of behind the ear hearing support technology holds, the number of choices are endless
