Washington, Sep 24 (PTI) Scientists, including one of Indian-origin, have designed an ultra-low-cost hearing aid that could be built with cheaply available open-source parts, an innovation that can help hundreds of millions of older people worldwide who can't afford existing forms of the sound amplifying device. "The challenge we set for ourselves was to build a minimalist hearing aid, determine how good it would be and ask how useful it would be to the millions of people who could use it," said study co-author M. Saad Bhamla, an assistant professor in the School of Chemical and Biomolecular Engineering at the Georgia Institute of Technology in the US.

The prototype, known as LoCHAid and described in the journal PLOS ONE, is expected to meet most of the targets set by the World Health Organization (WHO) for hearing aids aimed at mild-to-moderate age-related hearing loss, the researchers said.
