This map shows modeled outdoor noise across Overbrook 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 1,839 Overbrook residents, or 66.0%, live above that level. By land area, 71.8% of Overbrook is above 55 dBA.

Noise by Part of Overbrook
Average noise levels for Overbrook residents, grouped by direction from the center of Overbrook. The highest population-weighted average is in northwestern Overbrook; the lowest is in southwestern Overbrook, where just 54% of residents live in blocks above the EPA's 55 dBA threshold, roughly the same as the share in the loudest section.

Normal conversation an arm’s length away
To the human ear, noise in northwestern Overbrook sounds about 123% louder than in southwestern Overbrook, a 11.6 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 Clairton BL do you need to be?
Clairton BL 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 Overbrook sits under tree canopy (heavier than most neighborhoods) and roughly 38% 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 Overbrook. 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 northwest of Overbrook. 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 65 dBA on the map's Overall layer. Blocks on the opposite side of Overbrook, particularly to the southeast, show no measurable aviation contribution. Use the Aviation toggle on the map above to isolate the airport's footprint.
How Noise Is Distributed Across Overbrook
The bar chart below shows the share of Overbrook residents in each noise band. About 22% of residents live below the EPA's 55 dBA threshold, and roughly 19% live in blocks above 60 dBA. Long-term exposure in that range is linked to elevated stress hormones and cardiovascular risk.
How Overbrook Compares
Overbrook sits at the quieter end of the spectrum. Below: how Overbrook's average outdoor noise and share of residents above the EPA threshold compare with Perry South, Marshall-Shadeland, West Oakland, and Garfield.
Average noise level (dBA)
Overbrook's 57.3 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 Overbrook because most of either area is rural land away from major roads.
Share of residents above 55 dBA
About 66.0% of Overbrook 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, 71.8% of Overbrook'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 Overbrook
- 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 Clairton 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 31% of Overbrook is under tree cover (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. Pittsburgh International's approach paths concentrate aviation noise to the northwest. Neighborhoods to the southeast of downtown show no measurable contribution from the airport.
