Hearing
aids - this is a chance for people who are deaf or who are using the tinnitus
instrument, hear the sounds of the surrounding world. Hence the
question: how to choose a hearing aid, should be taken with the utmost
seriousness and scrupulousness. Hearing aids - especially individual device, so
you should not rely only on the free advice of the seller, it is better to seek
help from a specialist - a doctor, audiologist.
How to
choose the device to optimize the hearing, like the volume
amplifier, which would be the most suited, gave joy to hear the world
around us and to be comfortable with it? It is necessary to determine what type
of device suits you, what power is needed, as far as is necessary to amplify
sounds. You also need to evaluate how much you are willing to spend on the
apparatus.
Illiterate
selected hearing aid not only does not give an opportunity to hear, but can
also exacerbate the problem of hearing is also important to decide on the issue
of how many devices you need. Binaural hearing aids has a number of benefits -
optimizing localization, making it legible (if difficult acoustics), allows you
to work both ears simultaneously. But it is recommended not to all binaural
prosthetics. Some can not afford a high price since the device.
All such
devices by the method of processing an incoming audio signal is divided into
analog and digital. The operating principle of analog hearing aids is very
simple - using them is amplified all the surrounding sounds and vibrations
without isolation of human speech and the suppression of unwanted noise (eg,
wind noise, background noise). Analog phones - this last century, the only
advantage is their low cost.
Digital
devices - a new generation of accessories that are perfect for people with
varying degrees of hearing loss of all ages. These devices differ in a variety
of design, power and have the maximum opportunities in the correction of
hearing.
The main
objective of the instrument - sound amplification, filtering them from external
noise while improving sound quality. At the heart of the digital device is an
electronic processor and digital converter that allows you to process sounds
using complex algorithms.
