Decibel Shield's US City Noise Map ranks the noise level of every US city over 100,000 residents using the federal US DOT/BTS National Transportation Noise Map. It surfaces a counterintuitive finding (Inglewood, CA is loudest; New York City ranks about 47th) and is free to explore with no signup. The underlying city data is published under CC BY 4.0 so anyone can reuse it with attribution. The broader site also offers a free in-browser decibel meter and hearing tests.
