What
is the latest technique in hearing – aids?
These
hearing – aids work on the digital technology.
What
is the difference between the conventional and the digitally
programmed hearing – aids?
Programmable
hearing – aids are far more advanced that the conventional
types. These types of hearing – aids incorporate integrated
circuits with a memory chip that can store necessary information.
Unlike conventional types, these hearing – aids can be
modified with the help of a software fed into a computer. Thus
the number of parameters that can be altered are relatively
more in programmable hearing – aid.
What
are digital hearing – aids?
In
a digital hearing – aid, the incoming signals are converted
to digital signals. This "digitalization" makes its
possible to precisely analyze & filter the signals. The
signals can be processed in one or more frequency channels.
At the end, the digital signal is again converted to its analog
form.
What
are the advantages of a digital hearing – aid?
The
advantages are: -
- The
signal analysis is more sophisticated i.e. there is noise
reduction & speech enhancement.
- The
internal noise of the hearing – aid is reduced.
- It
provides "relaxed listening" in noisy listening
environments.
What
are the benefits to the user?
- Improvement
in quality of life.
- Improvement
in sound quality.
- Higher
listening comfort.
- Better
communication in noisy environment.
- Better
speech intelligibility in group conversations.
- More
flexibility in case of progressive hearing less.
