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 1,986 Mays Chapel Village residents, or 41.5%, live above that level. By land area, 48.4% of Mays Chapel Village is above 55 dBA.
Average noise levels for Mays Chapel Village residents, grouped by direction from the center of Mays Chapel Village. Central Mays Chapel Village carries the highest population-weighted average; Western Mays Chapel Village carries the lowest. Just 34% of residents in Western Mays Chapel Village live in blocks above the EPA's 55 dBA threshold, three-quarters of the share in Central Mays Chapel Village.

QuietLoud
Central Mays Chapel Village sounds about 36% louder than Western Mays Chapel Village to the human ear, a 4.4 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 Harrisburg Expy do you need to be?
Harrisburg Expy 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 soft rainfall.

Calculated from the model's calibrated attenuation formula. About 56% of Mays Chapel Village sits under tree canopy (much heavier than most neighborhoods) and roughly 22% 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 south of Mays Chapel Village. 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 Mays Chapel Village, 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 Mays Chapel Village
The bar chart below shows the share of Mays Chapel Village residents in each noise band. About 55% of residents live below the EPA's 55 dBA threshold, and roughly 26% live in blocks above 60 dBA. Long-term exposure in that range is linked to elevated stress hormones and cardiovascular risk.
How Mays Chapel Village Compares
Mays Chapel Village sits the highest among the peer group. Below: how Mays Chapel Village's average outdoor noise and share of residents above the EPA threshold compare with Town and Country North, Garrison, Rodgers Forge, and Forest Park.
Average noise level (dBA)
Mays Chapel Village's 58.2 dBA pop-weighted average is the highest among the peer group. Maryland as a whole averages 52.3 dBA and the U.S. averages 52.0 dBA. Both are lower than Mays Chapel Village because most of either area is rural land away from major roads.
Share of residents above 55 dBA
About 41.5% of Mays Chapel Village residents live in blocks where outdoor levels exceed the EPA's 55 dBA threshold. That's more than any of its peer group. Measured by land area instead, 48.4% of Mays Chapel Village'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 Mays Chapel Village
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 Harrisburg Expy 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 56% of Mays Chapel Village is under tree cover (much heavier than most neighborhoods), 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 south. Neighborhoods to the north 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.
