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 2,632 Cool Springs residents, or 97.2%, live above that level. By land area, 96.1% of Cool Springs is above 55 dBA.
Average noise levels for Cool Springs residents, grouped by direction from the center of Cool Springs. Northern Cool Springs carries the highest population-weighted average; Western Cool Springs carries the lowest. Just 100% of residents in Western Cool Springs live in blocks above the EPA's 55 dBA threshold, roughly the same as the share in Northern Cool Springs.

QuietLoud
Northern Cool Springs sounds about 103% louder than Western Cool Springs to the human ear, a 10.2 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 US Hwy 202 do you need to be?
US Hwy 202 produces an estimated 75 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 14% of Cool Springs sits under tree canopy (about average for neighborhoods) and roughly 68% 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
Philadelphia International (PHL) sits northeast of Cool Springs. 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 Cool Springs, particularly to the southwest, show no measurable aviation contribution. Use the Aviation toggle on the map above to isolate the airport's footprint.
How Noise Is Distributed Across Cool Springs
The bar chart below shows the share of Cool Springs residents in each noise band. About 0% of residents live below the EPA's 55 dBA threshold, and roughly 86% live in blocks above 60 dBA. Long-term exposure in that range is linked to elevated stress hormones and cardiovascular risk.
How Cool Springs Compares
Cool Springs sits the highest among the peer group. Below: how Cool Springs's average outdoor noise and share of residents above the EPA threshold compare with 9th Ward, Hedgeville, Highlands, and Browntown.
Average noise level (dBA)
Cool Springs's 63.1 dBA pop-weighted average is the highest among the peer group. Delaware as a whole averages 53.5 dBA and the U.S. averages 52.0 dBA. Both are lower than Cool Springs because most of either area is rural land away from major roads.
Share of residents above 55 dBA
About 97.2% of Cool Springs 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, 96.1% of Cool Springs's footprint sits above 55 dBA, against a Delaware average of 38.3% and a national average of 28.1%.
What This Means if You're Moving to Cool Springs
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 US Hwy 202 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 14% of Cool Springs is under tree cover (about average for 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. Philadelphia International's approach paths concentrate aviation noise to the northeast. Neighborhoods to the southwest 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.
