Disability Sector : Hearing Impairments
Function : Hearing aids
Category of research : Making existing technology/product cost effective
Brief description of the product/ technology:
Considering the large number of hearing impaired people, Department of Electronics and Information Technology (DeitY), had funded the Design and Development of a Digital Programmable Hearing Aid. With years of focused research and development, C- DAC has developed the Digital Programmable Hearing Aid, TARANG, under this project. Hearing Aid with maximum 80 dB gain covers hearing impaired patients with mild, moderate and profound hearing loss. These Hearing Aids have been successfully field trialed all over the country by 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., on more than 400 patients under the guidance and supervision of professional audiologists and ENT specialists of the concerned institutions and hospitals.
TARANG is an affordable, reliable highly featured state-of-the-art Digital Programmable Hearing Aid using indigenously developed Application Specific Integrated Circuit (ASIC), namely, NAADA. Using sophisticated Digital Signal Processing techniques, the product offers superior and stable characteristics over a wider dynamic range.
It comes in two models:
1. TARANG Body Worn 100 HT (TBW 100HT)
2. TARANG Behind the Ear 100 (TBE 100)
SHRUTHI PC software is used as the programming platform to program the hearing aid according to the individual needs. TARANG can be customized by an Audiologist, using SHRUTHI Software, to provide near normal hearing to the patient. TARANG works on a rechargeable Ni-MH battery for Body Worn version and Zn-Air battery for Behind-the-Ear model. The lesser number of components and compact design enables easy manufacturability. Also the use of rechargeable battery makes the cost of ownership affordable.
TARANG Hearing Aid will be avilabe for online purchase from CDAC website from 1st of December 2014.
C-DAC has won the NATIONAL AWARD FOR THE EMPOWERMENT OF PERSONS WITH DISABILITIES, 2012 instituted by the Ministry of Social Justice & Empowerment, Govt. of India, under the category of BEST APPLIED RESEARCH / INNOVATION / PRODUCT DEVELOPMENT AIMED AT IMPROVING THE LIFE OF PERSONS WITH DISABILITIES.
