It wouldn't just be noise though, some of the most dangerous vehicles are those associate with building sites (dump trucks, cement mixers, scaffold), so potentially it could mean whole building sites going onto night work, i'm no enginner but i know cement has a set time to be mixed and laid, then that will knock on the the cement works too. Also that industry may argue that it is already the most dangerous industry to work in and forcing it to work at night would increase the risk to it's workers etc.
That is a good point, but as I mentioned above, such bans always need justified exemptions.
