Presently audiological investigations are done in a
speciality hospital and the test results are analyzed and diagnosed
by the audiologists. However, the fact remains that most of us do
not undergo regular checking for hearing due to the reasons of
inconvenient timing and ease of accessibility. The object of this
work is to design and develop a computerized audiometer, which
could be effectively nsed for mass screening of level of hearing
impairment instead of the conventional audiometer. This would
be nser friendly, cost effective and efficient in terms of analysis,
data storage and maintenance. The present work successfully
enables subjects to conduct hearing screening tests fully with the
help of multimedia computers without any additional accessories.
The audiological tests could be conducted regularly so as to
facilitate the early detection of hearing loss at home or any place
and time convenient to the user. At first, the design requirements
for a digital hearing aid is being arrived by nsing the standard
Real Ear Insertion Gain (REIG) formulae followed in Anstralia
and European countries. Subsequently, based on the estimated
value of minimum threshold of hearing arrived from this
proposed set up, in addition to inputs from expert audiologists,
the REIG formula could be made distinct for every language.
