Within that, 1.2% face the most severe band — 70 dB or louder, the level at which sustained exposure starts damaging hearing. A further 41.3% sit in the 45–60 dB band — a noticeable background hum rather than a hearing risk. Overall the city ranks #114 of 297, above the national median.

On the map, green tracts are the quietest and red tracts the loudest, with each colored by the share of its own residents above 60 dB — so you can see exactly which parts of New Haven carry the noise. The loudest tracts track the city's busiest road, rail and flight corridors. These are measured values from the US DOT's 2020 National Transportation Noise Map paired with Census population, aggregated to tracts by the University of Washington — real data per tract, no interpolation and no estimate.

How this map is made
This is a transparent aggregation of federal data, not an estimate: the BTS 2020 National Transportation Noise Map (road + rail + aviation) overlaid with Census ACS 2016–2020 population at tract level, clipped to the city boundary. Full methodology, limitations and the free CSV/JSON are on the US cities noise ranking. Remember what it doesn’t count: sirens, construction, nightlife and neighbors are outside the model.
