How the quiet score works
Every nearby noise source is weighted by type, by how far it is from San Francisco Marriott Union Square, and by how often it's actually loud — a stadium or helipad counts far less than a motorway that never stops. The score is an estimate of the surroundings, not a decibel measurement, and it can't know which way your room faces or how well it's soundproofed. It's calibrated relative to the hotels we track, so treat it as a comparison tool and use the map above to judge the details yourself.
