This map shows modeled outdoor noise across Brighton Heights 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 4,328 Brighton Heights residents, or 73.9%, live above that level. By land area, 75.5% of Brighton Heights is above 55 dBA.

Noise by Part of Brighton Heights
Average noise levels for Brighton Heights residents, grouped by direction from the center of Brighton Heights. The highest population-weighted average is in western Brighton Heights; the lowest is in northeastern Brighton Heights, where just 39% of residents live in blocks above the EPA's 55 dBA threshold, about half the share in the loudest section.
Western Brighton Heights
88% of people above 55 dBA
Southern Brighton Heights
93% of people above 55 dBA
Southeastern Brighton Heights
79% of people above 55 dBA
Northern Brighton Heights
46% of people above 55 dBA
Northeastern Brighton Heights
39% of people above 55 dBA
To the human ear, noise in western Brighton Heights sounds about 85% louder than in northeastern Brighton Heights, a 8.9 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.
Rail Noise
Active freight rail runs through parts of Brighton Heights. 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.
Airport Noise
Pittsburgh International (PIT) sits west of Brighton Heights. 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 45 dBA on the map's Overall layer. Blocks on the opposite side of Brighton Heights, particularly to the east, show no measurable aviation contribution. Use the Aviation toggle on the map above to isolate the airport's footprint.
How Noise Is Distributed Across Brighton Heights
The bar chart below shows the share of Brighton Heights residents in each noise band. About 12% of residents live below the EPA's 55 dBA threshold, and roughly 30% live in blocks above 60 dBA. Long-term exposure in that range is linked to elevated stress hormones and cardiovascular risk.
How Brighton Heights Compares
Brighton Heights sits at the quieter end of the spectrum. Below: how Brighton Heights's average outdoor noise and share of residents above the EPA threshold compare with Beechview, Bluff, Bloomfield, and Mount Washington.
Average noise level (dBA)
Brighton Heights's 58.5 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 Brighton Heights because most of either area is rural land away from major roads.
Share of residents above 55 dBA
About 73.9% of Brighton Heights 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, 75.5% of Brighton Heights'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 Brighton Heights
- 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 Ohio River BL 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 Brighton Heights is under tree cover (heavier than most 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. Pittsburgh International's approach paths concentrate aviation noise to the west. Neighborhoods to the east 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.
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.
