The map below combines two data sources: the official U.S. DOT National Transportation Noise Map (modeled 24-hour average road, rail, and aviation noise — the colored bands) and real decibel readings measured by DecibelMap users (the dots). Drag and zoom to explore any neighborhood.
Colored bands: modeled traffic noise, quieter → louder (yellow 45 dB → orange → red → pink → purple → blue 90+ dB). Source: U.S. DOT Bureau of Transportation Statistics, 2022. Dots: crowdsourced readings.
