You really just need the noise ordinance to have more teeth... instead of just a perpetual fine, you need to be able to shut them down if they continue to exceed the noise threshold.

A fine is perfectly adequate to address the problem, provided you're able to enforce it.

Each time a repeat offender offends, simply double the fine from their last offense. Repeat monthly until their insolvency, at which point you confiscate the building and sell it to someone willing to follow the law.

I think that's a weird problem with law in general.

Corporations created by "incorporation", creating a "body" with all the rights of a human, are rarely treated with common sense punishments when they do wrong.

Humans do bad things, and they are not only fined, but forfeit rights, are segregated from others, put in jail, and sometimes executed.
