There's an argument that outside of actual safety issues, maybe it's best to leave this up to the market. My wife and I looked at a house once in Padova, where we lived, that was right next to the train tracks. You couldn't help but feel the trains go by, let alone hearing them. It was not for us, but it was super cheap, and might have been an option for someone without a lot of other good options - or a great option for someone hearing impaired who didn't care too much.
