According to the NIDCD, 15% of American adults (37.5 million) report some trouble hearing, yet only 1 in 5 people that would benefit from a hearing aid use one. Sound Sustainability’s online hearing screening removes barriers preventing people from determining whether they have hearing loss. To do this, we worked with audiologists to produce a free, easy-to-use, hearing screening that has users listen and respond to a series of tones played at different frequencies and decibels. Our goal is to allow people concerned for their hearing health to quickly check their hearing within the comfort of their own homes.
