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 1,029 1st Ward residents, or 67.4%, live above that level. By land area, 58.2% of 1st Ward is above 55 dBA.
Average noise levels for 1st Ward residents, grouped by direction from the center of 1st Ward. Southern 1st Ward carries the highest population-weighted average; Central 1st Ward carries the lowest. Just 58% of residents in Central 1st Ward live in blocks above the EPA's 55 dBA threshold, about two-thirds of the share in Southern 1st Ward.

QuietLoud
Southern 1st Ward sounds about 48% louder than Central 1st Ward to the human ear, a 5.7 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 81 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 quiet suburban street at night.

Soft rainfall
Calculated from the model's calibrated attenuation formula. About 8% of 1st Ward sits under tree canopy (lighter than most neighborhoods) and roughly 75% 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 1st Ward. 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 1st Ward
The bar chart below shows the share of 1st Ward residents in each noise band. About 28% of residents live below the EPA's 55 dBA threshold, and roughly 36% live in blocks above 60 dBA. Long-term exposure in that range is linked to elevated stress hormones and cardiovascular risk.
How 1st Ward Compares
1st Ward sits the lowest among the peer group. Below: how 1st Ward's average outdoor noise and share of residents above the EPA threshold compare with NoTi, hamilton-district-allentown-pa, hilltown-allentown-pa, and Downtown.
Average noise level (dBA)
1st Ward's 57.0 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 1st Ward because most of either area is rural land away from major roads.
Share of residents above 55 dBA
About 67.4% of 1st Ward 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, 58.2% of 1st Ward'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 1st Ward
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 8% of 1st Ward is under tree cover (lighter than most neighborhoods), and the dominant land cover is high-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.
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.
