New smartphone apps that link to hearing aids are helping people with impaired hearing to pump up the volume on their devices or to use them as headphones to stream phone calls, YouTube videos and music, according to Reuters.
About 36 million American adults have some hearing loss, according to the National Institute of Deafness and Other Communication Disorders. But only a fifth of people who could benefit from a hearing aid wear one.
"People will always need really good hearing aids, but moving forward, what will differentiate competitors will be connectivity (to smartphones), and it will need apps," Lars Viksmoen, chief executive of GN ReSound, a maker of hearing aids based in Denmark, said in a telephone interview.
