The law doesn't have to require something to make it not a good idea. My point was, I'm not deaf, but I'm fairly sure that on average deaf people are much better adapted to life with limited hearing than you or I would be when wearing ear buds. It doesn't logically follow that because a deaf person is allowed to drive we should be able to artificially reduce our hearing ability while driving.
