Major Research Output

Technologies successfully developed and transferred/demonstrated include:

Digital Programmable Hearing Aid

An ASIC based Digital Programmable Hearing Aid (DPHA) named TARANG along with hearing aid programming software has been designed and developed by CDAC Thiruvananthapuram. TARANG, available as Body-Worn (BW) and Behind-the-Ear (BTE) models, is suitable for hearing impaired patients with mild, moderate and profound hearing loss. The project won the National Award instituted by Ministry of Social Justice & Empowerment, Govt. of India for "Development of Best product and technology to empower physically impaired persons". The technology has been transferred to M/S Best Hearing Solutions, Delhi and M/S Keltron, Kerala and over 50,000 units have been sold till date.
