This map shows modeled outdoor noise across Biedeman 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 719 Biedeman residents, or 20.7%, live above that level. By land area, 20.8% of Biedeman is above 55 dBA.

Noise by Part of Biedeman
Average noise levels for Biedeman residents, grouped by direction from the center of Biedeman. The highest population-weighted average is in central Biedeman; the lowest is in northeastern Biedeman, where just 11% of residents live in blocks above the EPA's 55 dBA threshold, about two-thirds of the share in the loudest section.

Quiet office
To the human ear, noise in central Biedeman sounds about 32% louder than in northeastern Biedeman, a 4.0 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 93 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 office to normal conversation.

Calculated from the model's calibrated attenuation formula. About 18% of Biedeman sits under tree canopy (about average for neighborhoods) and roughly 52% 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 Biedeman. 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
Philadelphia International (PHL) sits southwest of Biedeman. The U.S. Department of Transportation measures aviation noise around this airport directly, 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 75 dBA on the map's Overall layer. Blocks on the opposite side of Biedeman, particularly to the northeast, show no measurable aviation contribution. Use the Aviation toggle on the map above to isolate the airport's footprint.
How Noise Is Distributed Across Biedeman
The bar chart below shows the share of Biedeman residents in each noise band. About 79% of residents live below the EPA's 55 dBA threshold, and roughly 4% live in blocks above 60 dBA. Long-term exposure in that range is linked to elevated stress hormones and cardiovascular risk.
How Biedeman Compares
Biedeman sits at the quieter end of the spectrum. Below: how Biedeman's average outdoor noise and share of residents above the EPA threshold compare with Marlton, Pyne Poynt, Parkside, and Stockton.
Average noise level (dBA)
Biedeman's 49.0 dBA pop-weighted average is at the quieter end of the spectrum. New Jersey as a whole averages 49.8 dBA and the U.S. averages 52.0 dBA. Both are lower than Biedeman because most of either area is rural land away from major roads.
Share of residents above 55 dBA
About 20.7% of Biedeman 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, 20.8% of Biedeman's footprint sits above 55 dBA, against a New Jersey average of 25.2% and a national average of 28.1%.
What This Means if You're Moving to Biedeman
- 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 18% of Biedeman is under tree cover (about average for 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. Philadelphia International's approach paths concentrate aviation noise to the southwest. Neighborhoods to the northeast of downtown show no measurable contribution from the airport.
