They should ask Berlin for advice. I've got a tram like right outside my window, and the trams are only audible right before the rails get ground back into shape; busses pass me regularly and I don't notice unless I'm looking.
The sirens from the emergency vehicles on the other hand, those are probably part of the reason why I'm tired all the time.
Emergency sirens being so loud is an unfortunate consequence of how good sound isolation is in contemporary cars.
Unfortunately I don’t know of an easy solution to this. Perhaps vehicles should be required to rebroadcast emergency sirens internally? Or maybe it will solve itself when electric cars reduce road noise.
