As per Census India Report 2011, about 5.07 million of total disabled population in India are hearing impaired. Considering the large number of hearing impaired people Department of Information Technology (DIT), Ministry of Communications and Information Technology (MCIT), had funded Design and Development of Digital Programmable Hearing Aid (DPHA).
Under this project, Hardware Design Group of C-DAC, Thiruvananthapuram, has successfully designed and fabricated a million gate Application Specific IC, NAADA, in 130nm technology. Using this NAADA IC, both Body Worn and Behind the Ear type Hearing Aids TARANG, have been developed, with maximum 80 dB gain, covering hearing impaired patients with mild, moderate and profound hearing loss. Country wide field trials successfully carried out in leading medical institutions and hospitals like All India Institute of Medical Sciences (AIIMS), New Delhi, All India Institute of Speech and Hearing (AIISH), Mysore, Ali Yavar Jung National Institute of Hearing Handicapped (AYJNIHH), Mumbai, Christian Medical College (CMC), Vellore, Madras ENT Research Foundation (MERF), Chennai, Govt. Medical College, Calicut etc, under the guidance and supervision of professional audiologists and ENT specialists.
The features of ”TARANG” Hearing Aid are as follows:
A software package, SHRUTHI with a Hardware Programming Interface module for programming TARANG has also been developed. This provides the audiologist with the Graphical User Interface and database required to enter and store the client specific data, audiological data and hearing instrument data. This interface and the communication protocol is an indigenous development and hence a low-cost alternative to the other expensive programming solutions available in the market. The software also provides the audiologist an-easy-to-use platform to program/modify TARANG with the help of a computer and the hardware interface module. With the development of the complete ecosystem, it is very easy for the audiologist to program the Hearing Aid in the field itself.
The unique feature of this developmental effort is the full ecosystem developed by the C-DAC team right from the ASIC, the Hearing Aid, SHRUTHI software for programming the Hearing Aid as per the patient’s profile to the Hardware Programming Interface module. A trained person can program the Hearing Aid in the field using his Computer if the patient’s audiogram is available. BIS certification is taken for the Body Level Hearing Aid. Applied for BIS certification of BTE Hearing Aid.
Project has won National Award for the Empowerment of Persons with Disabilities, in 2012 instituted by the Department of Disability Affairs, Ministry of Social Justice and Empowerment , Government of India.
