Montgomery's 56 census tracts span the full range of the federal noise map. Of its 183,087 residents, 4.2% are exposed to 60 dB or more of average-day road, rail and aviation noise. Within that, 1.2% face the most severe band — 70 dB or louder, the level at which sustained exposure starts damaging hearing. A further 17.9% sit in the 45–60 dB band — a noticeable background hum rather than a hearing risk. Overall the city ranks #182 of 297, below the national median — quieter than most big US cities.
Among Alabama's 4 cities of 100,000+ residents, Montgomery is the 4th-loudest. Nationally it sits just below Raleigh, NC (#181) and just above Denver, CO (#183).
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 Montgomery 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.
