DIGITAL
HEARING AID-
Modern
technology offers tremendous possibilities in terms
of functionality and cost-effectiveness to surmount
the inordinate difficulties faced by the hearing impaired
as a result of unaffordable and substandard products
based on analog technology.
The
DHA-I is a low cost, highly featured Digital Hearing
Aid using the ASIC technology developed by ER&DCI.
Advanced Digital Signal Processing techniques ensure
superior and stable amplification characteristic over
a wide dynamic range. The Digital Volume Control eliminates
the crackling and popping noise problems characteristic
of conventional hearing aids. Frequency dependent filtering
finely matches the audiogram of the specific user.
The individual hearing profile is reconfigurable to
accommodate hearing losses, which may occur in future.
All this high technology is made available in a remarkably
low-cost, low-power package, thanks to the advanced
CMOS ASIC implementation. Working on just two AA cells,
easily available along the length and breadth of our
country, DHA-I accomplishes a blend of low cost of ownership
and maintenance as well as superior performance over
a long operating life.
