Noise Levels in Woodley Park, Washington, DC | Find Quiet Neighborhoods With Our Sound Map

Population Above the EPA Outdoor Threshold

The EPA's 55 dBA outdoor reference level is a common benchmark for residential noise exposure, especially for activity interference, annoyance, and long-term community noise concerns. About 3,678 Woodley Park residents, or 51.7%, live above that level. By land area, 54.8% of Woodley Park is above 55 dBA.

Noise by Part of Woodley Park

Average noise levels for Woodley Park residents, grouped by direction from the center of Woodley Park. The highest population-weighted average is in northern Woodley Park; the lowest is in western Woodley Park, where just 40% of residents live in blocks above the EPA's 55 dBA threshold, roughly the same as the share in the loudest section.

To the human ear, noise in northern Woodley Park sounds about 12% louder than in western Woodley Park, a 1.6 dBA gap. Every 10 dBA roughly doubles perceived loudness. Within any of these directions, two homes a quarter mile apart can still differ by 10 or more dBA depending on how close they sit to a major highway.

Airport Noise

Ronald Reagan Washington Ntl (DCA) sits south of Woodley Park. The U.S. Department of Transportation measures aviation noise around this airport directly, and the model uses those federal measurements rather than synthetic predictions.

Blocks under the approach and departure paths carry combined road-plus-aviation noise, with some exceeding 45 dBA on the map's Overall layer. Blocks on the opposite side of Woodley Park, particularly to the north, show no measurable aviation contribution. Use the Aviation toggle on the map above to isolate the airport's footprint.

How Noise Is Distributed Across Woodley Park

The bar chart below shows the share of Woodley Park residents in each noise band. About 38% of residents live below the EPA's 55 dBA threshold, and roughly 15% live in blocks above 60 dBA. Long-term exposure in that range is linked to elevated stress hormones and cardiovascular risk.

How Woodley Park Compares

Woodley Park sits at the quieter end of the spectrum. Below: how Woodley Park's average outdoor noise and share of residents above the EPA threshold compare with Barnaby Woods, Mt Vernon Square, Downtown, and Hill East.

Average noise level (dBA)

Woodley Park's 56.1 dBA pop-weighted average is at the quieter end of the spectrum. District of Columbia as a whole averages 57.1 dBA and the U.S. averages 52.0 dBA. Both are lower than Woodley Park because most of either area is rural land away from major roads.

Share of residents above 55 dBA

About 51.7% of Woodley Park residents live in blocks where outdoor levels exceed the EPA's 55 dBA threshold. That's in the middle of its peer group. Measured by land area instead, 54.8% of Woodley Park's footprint sits above 55 dBA, against a District of Columbia average of 60.6% and a national average of 28.1%.

What This Means if You're Moving to Woodley Park

• Distance from highways matters more than the neighborhood name. Two homes in the same zip code can differ by 20 dBA if one sits 100 meters from Cathedral Ave NW and the other 500 meters away. The model captures this at 100-meter resolution, so noise exposure changes block by block.
• Tree canopy can help reduce modeled noise exposure. Roughly 8% of Woodley Park is under tree cover (lighter than most neighborhoods), and the dominant land cover is medium-intensity developed land. Both are measured from federal USDA Forest Service and USGS satellite imagery at 30-meter resolution. Streets with 60% or higher canopy show 3 to 5 dBA lower noise than comparable streets with bare ground or pavement, which is why the per-place decay rate above already accounts for it.
• Airport noise is directional. Ronald Reagan Washington Ntl's approach paths concentrate aviation noise to the south. Neighborhoods to the north of downtown show no measurable contribution from the airport.
