The difference between deafness and any other disability is that there is no way to put yourself in a position of knowing what it would be like because you can't stop yourself from hearing your own breath or your own heartbeat. You can not remove sound entirely from your life. You can get a sense of what being blind is like by closing and covering your eyes which provides a source of empathy because we can all project ourselves to that. But people who think they can project themselves into deafness are mistaken because you can't.
