Hey HN, I build "How Loud Is My Hotel?" as a simple way to check for possible loud noise near a hotel (or any other address) before booking it. I've had some negative experiences in the past so this automatically checks for things like nearby Clubs, Police Stations with sirens, big roads, railroads etc. and gives you a "noise score" based on them. It's free, works worldwide and needs no account. It estimates outside noise risk rather than measuring decibels, so building insulation and temporary noise aren’t included.
