This map shows modeled outdoor noise across 16635 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 2,117 16635 residents, or 21.7%, live above that level. By land area, 29.9% of 16635 is above 55 dBA.

Noise by Part of 16635
Average noise levels for 16635 residents, grouped by direction from the center of 16635. Eastern 16635 carries the highest population-weighted average; Western 16635 carries the lowest. Just 2% of residents in Western 16635 live in blocks above the EPA's 55 dBA threshold, a fifth of the share in Eastern 16635.
Central 16635
49% of people above 55 dBA
Eastern 16635
33% of people above 55 dBA
Northern 16635
24% of people above 55 dBA
Southern 16635
14% of people above 55 dBA
Western 16635
2% of people above 55 dBA
Eastern 16635 sounds about 107% louder than Western 16635 to the human ear, a 10.5 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.
Loudest Road Corridors
The model evaluates every road in 16635 using federal traffic counts, posted speeds, heavy-truck ratios, and pavement type. The source level shown is the modeled noise at the road centerline, where it is loudest. Noise drops with distance, faster in vegetated areas and slower over open pavement.
How far back from Bud Shuster Hw do you need to be?
Bud Shuster Hw produces an estimated 74 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 30% of 16635 sits under tree canopy (about average for zip codes) and roughly 19% 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.
Rail Noise
Active freight rail runs through parts of 16635. For most blocks the rail-only contribution is small. Combined road-plus-rail noise rarely exceeds road noise on its own. The exceptions are the handful of blocks within roughly a quarter mile of the right-of-way during pass-through hours.
Use the Rail toggle on the map above to isolate rail's contribution from road and aviation.
How Noise Is Distributed Across 16635
The bar chart below shows the share of 16635 residents in each noise band. About 71% of residents live below the EPA's 55 dBA threshold, and roughly 6% live in blocks above 60 dBA. Long-term exposure in that range is linked to elevated stress hormones and cardiovascular risk.
How 16635 Compares
16635 sits the highest among the peer group. Below: how 16635's average outdoor noise and share of residents above the EPA threshold compare with 16648, 16686, 15931, and 15963.
Average noise level (dBA)
16635's 50.2 dBA pop-weighted average is the highest among the peer group. Pennsylvania as a whole averages 52.9 dBA and the U.S. averages 52.0 dBA. Both are lower than 16635 because most of either area is rural land away from major roads.
Share of residents above 55 dBA
About 21.7% of 16635 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, 29.9% of 16635'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 16635
- 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 Bud Shuster Hw 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 30% of 16635 is under tree cover (about average for zip codes), 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.
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.
Federal datasets used:
FHWA Highway Performance Monitoring System: road geometry, traffic counts, lane configuration
U.S. DoT Bureau of Transportation Statistics National Transportation Noise Map: aviation and rail noise, road calibration ground truth
USGS / MRLC National Land Cover Database: land cover and impervious surface coverage
USDA Forest Service Tree Canopy Cover: vegetation density for sound propagation
U.S. Census Bureau TIGER/Line: block-level geography and population
U.S. EPA Levels Document: 55 dBA outdoor reference level
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.
