Digital BTE Hearing Aids Look Like Analog BTE Hearing Aids, But Are Smaller And More Effective
Every BTE (behind-the-ear) hearing aid comes with a microphone, ear hook, ear-mold, speaker and amplifier as well as a battery. When it concerns digital BTE hearing aids each manufacturer chooses different locations for the various parts including speakers, microphones, amplifiers and batteries though the newer as well as smaller digital BTE hearing aids do not come with an ear-mold but have instead a tiny sized dome or bud which has a few holes in it.
Smaller Than Analog BTE Hearing Aids
In essence, digital BTE hearing aids are very much like the analog counterparts - at least on the outside. However, digital BTE hearing aids comprise a hearing aid case as well as an ear-hook extension as well as a tube which connects to an ear-mold. Nevertheless, both digital BTE hearing aids and analog BTE hearing aids are almost of the same size though the digital variety are supposedly smaller in size.
Another feature of digital BTE hearing aids is that they can fit behind as well as over your ears and the ear hooks fit over the front of a person's ears and also points in the direction of the ear canal. At one end of a tube there is an ear hook connected while the other end connects to the ear-mold in back part of the canal.
DSP or Digital Signal Processing chip is a special feature in digital BTE hearing aids which is not found in analog BTE hearing aids and this chip is in fact the brain center of each digital BTE hearing aids. The DSP chips have micro-circuitry that is very similar to what is found in the CPU of modern computers and in addition, these chips also come with software programs that have been burnt into the chips.
Digital BTE hearing aids that comprise of DSP chips can do a number of things. For one, they have multiple frequency response bands that are very similar to equalizers that are commonly found on music systems. Then, there are multiple channels which a user can select in order to accommodate different sound environments. Other features of these DSP chips are inclusion of noise reduction filters, dynamic contrast detection as well as multiple microphones.
It will also pay to read digital hearing aids reviews as the high pace at which modern hearing aids are improving today makes it hard to stay abreast of each new improvement. It therefore makes more sense to get the views of experts who will inform you about salient features, prices, places where you can buy the digital hearing aids as well highlight important pros and cons of various makes and models.
