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 4,554 Colonial Park residents, or 34.6%, live above that level. By land area, 45.9% of Colonial Park is above 55 dBA.
Average noise levels for Colonial Park residents, grouped by direction from the center of Colonial Park. Western Colonial Park carries the highest population-weighted average; Eastern Colonial Park carries the lowest. Just 15% of residents in Eastern Colonial Park live in blocks above the EPA's 55 dBA threshold, a third of the share in Western Colonial Park.

QuietLoud
Western Colonial Park sounds about 111% louder than Eastern Colonial Park to the human ear, a 10.8 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 Jonestown Rd do you need to be?
Jonestown Rd produces an estimated 66 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 31% of Colonial Park sits under tree canopy (about average for cities) and roughly 33% 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
Harrisburg International (MDT) sits south of Colonial Park. The U.S. Department of Transportation models aviation noise around this airport from federal traffic data, 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 55 dBA on the map's Overall layer. Blocks on the opposite side of Colonial 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 Colonial Park
The bar chart below shows the share of Colonial Park residents in each noise band. About 60% of residents live below the EPA's 55 dBA threshold, and roughly 16% live in blocks above 60 dBA. Long-term exposure in that range is linked to elevated stress hormones and cardiovascular risk.
How Colonial Park Compares
Colonial Park sits at the quieter end of the spectrum. Below: how Colonial Park's average outdoor noise and share of residents above the EPA threshold compare with New Cumberland, Hershey, Progress, and Enola.
Average noise level (dBA)
Colonial Park's 54.6 dBA pop-weighted average is at the quieter end of the spectrum. Pennsylvania as a whole averages 52.9 dBA and the U.S. averages 52.0 dBA. Both are lower than Colonial Park because most of either area is rural land away from major roads.
Share of residents above 55 dBA
About 34.6% of Colonial 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, 45.9% of Colonial Park's footprint sits above 55 dBA, against a Pennsylvania average of 33.5% and a national average of 28.1%.
What This Means if You're Moving to Colonial 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 Jonestown Rd 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 31% of Colonial Park is under tree cover (about average for 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. Harrisburg International'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.
