Hearing aids do extremely well these days, thanks to digital technology that has been generally used since 1996.
A digital hearing aid is a gadget that processes sound waves into digital format before amplifying the sound for the client.
The most important advantage of a digital hearing aid is that it can amplify preferred voices more precisely. The most wonderful feature of a digital hearing aid is its capability to distinguish surroundings noises (radiators, fans, other people talking, etc.) from the noise or voice you have in mind to understand.
The main distinction between the old analog hearing aid and digital hearing aid is that an analog hearing aid magnifies the sound as it is , in order to make it louder, while a digital hearing aid divides the sounds waves , makes them better , combine them and finally amplifies them.
A digital hearing aid can be programmed so that the user hearing profile and needs can be fine tuned by a small computer .
Analog hearing aids are currently normally only issued as substitutions for present users of analog aids for whom a digital hearing aid is unsuitable.
A digital hearing aid containes front and rear microphones, a sound processor, and a speaker.
A digital hearing aid is the best hearing aid for old people who are losing their hearing due to aging.
Wearing a digital hearing aid is more easy today than it was few years ago because the technology is ever increasing.
Before you make a decision which type of digital hearing aid is best for you, you will need to speak to a certified audiologist. Digital technology gives the audiologist maximum control over sound quality and sound processing characteristics.
What is digital sound processing?
Digital sound processing is used to replicate the sound instead of an analog signal.
Digital technology uses directional microphones. Research has shown that digital hearing aid users who have directional microphones are 50% more pleased with the hearing aid’s performance in noise.
Battery:
The time the battery can last rely on the type of hearing aid, the dimension of the battery, and the amount of use the hearing aid receives.
By far, most use a zinc air button cell battery that is changed when finished by the user.
Please notice when changing the battery because it is easy to put the hearing aid battery in the opposite way so be sure that the + on the battery matches the + on the battery compartment door. Be cautious when shutting the hearing aid battery door and if you feel that it must be forced to shut, this is often an indication that the battery is in the wrong way.
One of the main drawbacks are finding other energy sources, but some that are under consideration are solar energy and small battery packs, which can be used for medical purposes as well as being more fashionable .
Accessories:
In recent years, manufactures have been doing a really amazing array of hearing aid accessories.
But since technology used within hearing aids differs, some hearing aid accessories will not really suit in the type of hearing aid that you are currently using.
There are many styles and models of digital hearing aids and hearing aids accessories available in the market today.
Costs:
The recommended retail prices can be as far as $5,000 (each). Digital and analog hearing devices are available in a variety of characteristics and prices.
