Sohum is an Auditory Evoked Potential acquisition system for resource constrained settings. 3 out of 1000 babies are born with hearing defects. In India, most of these cases go undiagnosed till the age of 2-3 years, when parents finally notice that their child does not speak. Lack of an affordable hearing screening test is one of the reasons. We developed Sohum at Stanford India Biodesign, AIIMS, Delhi for almost one and a half year while trying to raise funds to support development.
