This map shows modeled outdoor noise across 08751 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 439 08751 residents, or 18.5%, live above that level. By land area, 23.0% of 08751 is above 55 dBA.

Noise by Part of 08751
Average noise levels for 08751 residents, grouped by direction from the center of 08751. Western 08751 carries the highest population-weighted average; Eastern 08751 carries the lowest. Just 10% of residents in Eastern 08751 live in blocks above the EPA's 55 dBA threshold, a third of the share in Western 08751.
Central 08751
21% of people above 55 dBA
Eastern 08751
10% of people above 55 dBA
Northern 08751
17% of people above 55 dBA
Southern 08751
14% of people above 55 dBA
Western 08751
40% of people above 55 dBA
Western 08751 sounds about 141% louder than Eastern 08751 to the human ear, a 12.7 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 Nj 37 do you need to be?
Nj 37 produces an estimated 68 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 1% of 08751 sits under tree canopy (much lighter than most zip codes) and roughly 84% 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.
