Im looking for a movie, think its from after dark horror fest - but i've looked through all of em and werent able to find it..

A short summary of what i remember; its about a man that can hear everything louder than normal people, he can hear people grinding their teeths, and when they turn a page in a book - it may not sound too horror-like, but the sounds is really what makes it.. ALSO the most important part of the movie is that he can hear that hes son got a disfunction with hes heart..

Anyone who would be able to find it, or remember the title? sorry for my bad enlissh
