This map shows modeled outdoor noise across 08406 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 1,227 08406 residents, or 24.5%, live above that level. By land area, 24.2% of 08406 is above 55 dBA.

Noise by Part of 08406
Average noise levels for 08406 residents, grouped by direction from the center of 08406. The highest population-weighted average is in eastern 08406; the lowest is in western 08406, where just 2% of residents live in blocks above the EPA's 55 dBA threshold, a fifth of the share in the loudest section.
Eastern 08406
15% of people above 55 dBA
Northern 08406
10% of people above 55 dBA
Southwestern 08406
16% of people above 55 dBA
Northwestern 08406
4% of people above 55 dBA
Western 08406
2% of people above 55 dBA
To the human ear, noise in eastern 08406 sounds about 96% louder than in western 08406, a 9.7 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 Atlantic County 629 do you need to be?
Atlantic County 629 produces an estimated 63 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 3% of 08406 sits under tree canopy (much lighter than most zip codes) and roughly 74% 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.
