I think it's fine as long as you keep it low. Same with a car. One day I was blasting the stereo really loud in my car. I was sitting at a red light and when it turned green I started to go. Right before I entered the intersection a firetruck went screaming through, blowing the red light. I couldn't hear the damn siren until he was right on me. If he had come along a few seconds later, I would have been toast. I can't imagine how tough it would be for a deaf person on these crazy roads.
