According to reports, 230 million of the global population aged 65 and above suffer from a hearing deficiency, amongst other health issues. Similar was the condition of Saad Bhamla's grandparents when the now-researcher was an undergraduate, studying in Mumbai, India. At the time, he wanted to solve his grandparents' hearing issue with the pricey hearing-aid devices. However, those expensive healthcare devices were out-of-reach for Bhamla. Now, the man has developed one of the cheapest hearing-aid devices to help all of the country's senior population suffering from hearing deficiency.
