This map shows modeled outdoor noise across Nottingham at 100-meter resolution, combining road, aviation, and rail sources. Green areas measure below 45 dBA. Orange and red exceed the EPA's 55 dBA outdoor threshold linked to long-term health effects. Use the layer toggles to view each source on its own or all together.

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 3,139 Nottingham residents, or 29.2%, live above that level. By land area, 35.9% of Nottingham is above 55 dBA.
Average noise levels for Nottingham residents, grouped by direction from the center of Nottingham. Southern Nottingham carries the highest population-weighted average; Northern Nottingham carries the lowest. Just 7% of residents in Northern Nottingham live in blocks above the EPA's 55 dBA threshold, a fifth of the share in Southern Nottingham.

QuietLoud
Southern Nottingham sounds about 56% louder than Northern Nottingham to the human ear, a 6.4 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 John F Kennedy Memorial Hwy do you need to be?
John F Kennedy Memorial Hwy produces an estimated 80 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 office.

Soft rainfall
Calculated from the model's calibrated attenuation formula. About 44% of Nottingham sits under tree canopy (heavier than most cities) and roughly 27% 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
Baltimore/Washington International Thurgood Marshall (BWI) sits southwest of Nottingham. 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 Nottingham, 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 Nottingham
The bar chart below shows the share of Nottingham residents in each noise band. About 73% of residents live below the EPA's 55 dBA threshold, and roughly 13% live in blocks above 60 dBA. Long-term exposure in that range is linked to elevated stress hormones and cardiovascular risk.
How Nottingham Compares
Nottingham sits at the quieter end of the spectrum. Below: how Nottingham's average outdoor noise and share of residents above the EPA threshold compare with Overlea, White Marsh, Rossville, and Lutherville-Timonium.
Average noise level (dBA)
Nottingham's 53.1 dBA pop-weighted average is at the quieter end of the spectrum. Maryland as a whole averages 52.3 dBA and the U.S. averages 52.0 dBA. Both are lower than Nottingham because most of either area is rural land away from major roads.
Share of residents above 55 dBA
About 29.2% of Nottingham 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, 35.9% of Nottingham'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 Nottingham
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 John F Kennedy Memorial Hwy 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 44% of Nottingham is under tree cover (heavier than most cities), and the dominant land cover is low-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. Baltimore/Washington International Thurgood Marshall's approach paths concentrate aviation noise to the southwest. Neighborhoods to the northeast of downtown show no measurable contribution from the airport.
Sources & Methodology
The BestNeighborhood noise model is calibrated against nearly one million federal ground-truth measurements across four states. Road noise is computed from segment-level federal traffic data and propagated outward using physics-based acoustic decay, with attenuation rates that depend on the surrounding land cover.
All inputs are published federal datasets. Block-level noise is computed by combining road, rail, and aviation sound sources in the energy domain, the same physics used in professional environmental noise assessments. Read the full methodology.
