About 12 percent of Americans suffer from some form of hearing loss, according to the Center for Hearing and Communication, an organization that offers hearing tests and speech therapy. And yet aiding those people is far more complicated than simply increasing the volume on a device, because no two people have the same kind of hearing loss, explains Barbara Kelly, deputy director of the Hearing Loss Association of America. "Every hearing loss has a different fingerprint," she says.
A new smart-phone app called ACEHearing aims to address this via a simple test that diagnoses a user's specific form of hearing loss and customizes the output of a mobile device to better match the listener's ability to hear.
