How Loud Is Baltimore, MD?
BWI sits ten miles south of downtown with approaches over the Patapsco corridor, so the airport mostly affects Linthicum and the southern suburbs. In the city, I-83 runs elevated down the Jones Falls valley into downtown, and the Northeast Corridor rail line — one of the busiest in the country — cuts through the east-side rowhouse neighborhoods.

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.
