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 1,248 Mount Oliver residents, or 55.4%, live above that level. By land area, 65.2% of Mount Oliver is above 55 dBA.
Average noise levels for Mount Oliver residents, grouped by direction from the center of Mount Oliver. Western Mount Oliver carries the highest population-weighted average; Central Mount Oliver carries the lowest. Just 46% of residents in Central Mount Oliver live in blocks above the EPA's 55 dBA threshold, about half the share in Western Mount Oliver.

QuietLoud
Western Mount Oliver sounds about 43% louder than Central Mount Oliver to the human ear, a 5.2 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 do you need to be?
produces an estimated 64 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 19% of Mount Oliver sits under tree canopy (lighter than most cities) and roughly 54% 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
Pittsburgh International (PIT) sits northwest of Mount Oliver. 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 Mount Oliver, 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 Mount Oliver
The bar chart below shows the share of Mount Oliver residents in each noise band. About 33% of residents live below the EPA's 55 dBA threshold, and roughly 12% live in blocks above 60 dBA. Long-term exposure in that range is linked to elevated stress hormones and cardiovascular risk.
How Mount Oliver Compares
Mount Oliver sits the lowest among the peer group. Below: how Mount Oliver's average outdoor noise and share of residents above the EPA threshold compare with Etna, Millvale, Sharpsburg, and Aspinwall.
Average noise level (dBA)
Mount Oliver's 55.7 dBA pop-weighted average is the lowest among the peer group. Pennsylvania as a whole averages 52.9 dBA and the U.S. averages 52.0 dBA. Both are lower than Mount Oliver because most of either area is rural land away from major roads.
Share of residents above 55 dBA
About 55.4% of Mount Oliver residents live in blocks where outdoor levels exceed the EPA's 55 dBA threshold. That's fewer than any of its peer group. Measured by land area instead, 65.2% of Mount Oliver'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 Mount Oliver
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 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 19% of Mount Oliver is under tree cover (lighter than most cities), 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 northwest. Neighborhoods to the southeast 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.
