This is not good. The problem here is essentially social, or we might call it antisocial -- people simply not caring about the living beings around them. That can't actually be solved with technology, but you can definitely create technology to detect loud sounds and ticket people. This simultaneously enriches the state and helps tighten the noose of surveillance and control, while doing nothing about the root issue.
