I also have to say he can feel sounds through the air. Before I had his door light instead of doorbell installed he could feel us pounding on his door through the air. My brother is profoundly deaf which means he has no hearing at all. He has 2% in one ear and none in the other. Sometimes hearing can be feeling.Well...I have a deaf brother (seriously) but he can feel the vibrations of sounds through his feet? That's his way of hearing music and other sounds.?
