Those people that need to use hearing aids find that aids are available to fit on the different parts of or in the ear. There are different types of circuitry in hearing aids. The BTE Digial Hearing Aids uses the latest circuitry with the usual type of hearing device.
It was years before digital processing came about. When it did come out, it was too large and bulky to be practical at all. Once it was possible to use them, they were still impractical and it was only when the technology you get today arrived that circuits became tiny. BTE Digital Hearing Aids uses the advantage of this technology like many other hearing aids.
BTE actually means 'Behind the Ear'. The basic structure of the BTE Digital Hearing Aids are just like the usual BTE aids. There is an ear mould which custom made to fit inside a person's ear. The mould is hooked up to the hearing aid, which just sits behind the ear, using a tube known as the tone hook. The top of the hearing aid has a microphone for channeling sound into the aid. The controls are easy to use on the aid which is both durable and powerful.
BTE Digital Hearing Aids have come a long way from the analogue type that first came out. Try listening to an old vinyl record and compare that to a CD; you hear a distinctive sound difference that digital makes. There is so much more that the aid can do for you.
The function of the BTE Digital Hearing Aids converts the sound picked up from the microphone into computer bits, which are then processed at a surprisingly speedy rate. This is done by a processor called a DSP by the hearing aid industry, which is a digital signal processor.
The DSP works by sorting the sounds into channels of frequencies which are split into lower and higher pitches, that is what speech sounds are made up of. By not getting the full range of these audible frequencies, you will not be able to pick up all the sounds so what you will hear is jumbled up speech. With the BTE Digital Hearing Aids you are given the power to amplify the sound even more so that you distinguish voices much more easier.
These hearing aids treats continuous noise differently to how they process noises which have a shorter duration. For instance, the doorbell ringing would interest you more than the sound of an air conditioner running. Feedback is minimized through the circuitry and the ear mould which fits into the ear.
These hearing aids can also correct the problem of recruitment where a person that has a hearing loss finds that soft noises will sound too soft and also loud noises become too loud. With digital processing of the sound, this is all diminished. Some of these hearing aids come with two microphones so that the wearer can focus on the sound coming from the front, known as directionality. This is to provide less distraction which you can get from the environment surrounding you.
With a BTE Digital Hearing Aids offers the best of both worlds. They are durable enough and so easy that a child can use them, with the added advantage of the modern digital sound processing. It provides better hearing for most.
