Quiet office to normal conversation
Eastern Woodlawn Hayattsville sounds about 37% louder than Southern Woodlawn Hayattsville to the human ear, a 4.5 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.
How far back from do you need to be?
produces an estimated 77 dBA at its loudest centerline points. Noise drops logarithmically with distance, with the exact rate depending on what's between you and the road. Tree cover, walls, terrain, and pavement type all matter. At roughly a quarter mile back, traffic fades into the noise level of a quiet suburban street at night.

Soft rainfall
Calculated from the model's calibrated attenuation formula. About 34% of Woodlawn Hayattsville sits under tree canopy (much heavier than most neighborhoods) and roughly 44% is impervious surface like pavement and rooftops. Both are folded into the per-place decay rate above. Heavier canopy pulls noise down faster with distance; impervious surfaces slow the drop.

Airport Noise
Ronald Reagan Washington Ntl (DCA) sits southwest of Woodlawn Hayattsville. 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 75 dBA on the map's Overall layer. Blocks on the opposite side of Woodlawn Hayattsville, particularly to the northeast, show no measurable aviation contribution. Use the Aviation toggle on the map above to isolate the airport's footprint.
How Noise Is Distributed Across Woodlawn Hayattsville
The bar chart below shows the share of Woodlawn Hayattsville residents in each noise band. About 64% of residents live below the EPA's 55 dBA threshold, and roughly 10% live in blocks above 60 dBA. Long-term exposure in that range is linked to elevated stress hormones and cardiovascular risk.
How Woodlawn Hayattsville Compares
Woodlawn Hayattsville sits at the louder end of the spectrum. Below: how Woodlawn Hayattsville's average outdoor noise and share of residents above the EPA threshold compare with Walker Mill, Carroll Manor, Friendly, and Lanham-Seabrook.
Average noise level (dBA)
Woodlawn Hayattsville's 54.6 dBA pop-weighted average is at the louder end of the spectrum. Maryland as a whole averages 52.3 dBA and the U.S. averages 52.0 dBA. Both are lower than Woodlawn Hayattsville because most of either area is rural land away from major roads.
Share of residents above 55 dBA
About 38.0% of Woodlawn Hayattsville 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, 43.5% of Woodlawn Hayattsville's footprint sits above 55 dBA, against a Maryland average of 32.9% and a national average of 28.1%.
What This Means if You're Moving to Woodlawn Hayattsville
- 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 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 34% of Woodlawn Hayattsville is under tree cover (much heavier 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 southwest. Neighborhoods to the northeast of downtown show no measurable contribution from the airport.
