Electronic devices should have to dampen their sounds, in the consideration of other people, at least in public. Why should people be able to disturb others in such a fashion? It does not make any sense. We need to teach consideration and respect for others boundaries in public, which is sorely lacking in our society.
This day in age we should always be looking to what we can add to our devices that will benefit our way of life. Current electronic devices should be allowed to have sound-leveling/differentiating features in order to benefit their users. We should always be pushing technology to go further, not stifle it to stay where we are.
