DBT launches Sohum – an innovative newborn hearing screening device

The Honorable Minister of State, Ministry of Science and Technology & Earth Sciences, Shri Y.S. Chowdary, launched Sohum – the newborn hearing screening device developed by SIB startup M/s Sohum Innovation Labs India Pvt. Ltd. on July 17th, 2017 at Prithvi Bhavan. The indigenously developed Sohum was formally launched by the Minister in the presence of Prof. K. VijayRaghavan, Secretary DBT and other dignitaries, as a valuable contribution to the Make in India campaign of the Government.

This innovative medical device has been developed under Department of Biotechnology (DBT), Ministry of Science and Technology; Government of India supported School of International Biodesign (SIB). SIB is a flagship Program of the DBT aimed to develop innovative and affordable medical devices as per unmet clinical needs of India and to train the next generation of medical technology innovators in India. This Program is implemented jointly at AIIMS and IIT Delhi in collaboration with International partners. Biotech Consortium India Limited manages techno-legal activities of the Program.

Sohum is a low cost and unique device which uses brain stem auditory evoked response, the gold standard in auditory testing to check for hearing response in a newborn. As of now, this technology is prohibitively expensive and inaccessible to many. Start-up Sohum has made the technology appropriate for the resource constrained settings and aims to cater to nearly 26 million babies born every year in India.

One of the most common birth disorders – congenital hearing loss – is a result of both genetic and non-genetic factors. These factors are mostly associated with resource-poor economies such as India where, unlike advanced healthcare systems, hearing impairment goes undiagnosed. Thus, when it is discovered at 4+ years, it’s too late to reverse the damage and this leads to a host of problems such as impaired communication skills and even possible mental illness; all of which have a deep impact on the child, emotionally and economically life-long.

Globally, 800000 hearing impaired babies are born annually of which, nearly 100000 are in India. And all this preventable damage needs is early screening, which can facilitate timely treatment and rehabilitation. Sohum team has come up with a screening device to facilitate the routine screening of newborn babies – with the potential to help children at a key stage of their development.

The portable Sohum Hearing Screening measures auditory brain waves via three electrodes placed on the baby’s head. When stimulated, they detect electrical responses generated by the brain’s auditory system. If there is no response, the child cannot hear. The battery-operated device is non-invasive, which means babies do not need to be sedated, which is the current, and risky, testing in process at present.

Another key advantage over other testing systems is the patented, in-built algorithm that filters out ambient noise from the test signal. This is important because health clinics can be incredibly crowded and noisy. The device has been installed in five clinical centers, which are currently running the hearing screening program. The aim is to screen two percent of hospital-born babies in the first year, before scaling up. The project has ambitious plans – to help every baby born in India be screened.
