Well, not quite. Not showing your hair or not eating in public may have meaning in somebody's culture/religion, but it doesn't hurt anyone else either way. Playing video/music without earphones does. And surely people must have experienced it from the other side when people nearby were playing music they didn't care for. I think it is reasonable for people to ask themselves "Would I like it if someone near me did <X>?", and if the answer is 'No' to not do it themselves. Maybe this is "shame" or maybe simple empathy.
