Hearing Corrector is the desktop version of the hearing app "hearing help" for iPhone, iPad, and iPod. With age, by disease or due to an acoustic trauma, the hearing decreases. In most cases the high sound frequencies are particularly affected. But even the lower or certain individual frequencies can be insensitive and disturb the sound. With Hearing Corrector, your favorite music, audio-books, and any sound material can sound like before, when the hearing was still intact.
