This map shows modeled outdoor noise across 08202 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 45 08202 residents, or 9.0%, live above that level. By land area, 6.6% of 08202 is above 55 dBA.

Noise by Part of 08202
Average noise levels for 08202 residents, grouped by direction from the center of 08202. Northern 08202 carries the highest population-weighted average; Eastern 08202 carries the lowest. Just 5% of residents in Eastern 08202 live in blocks above the EPA's 55 dBA threshold, about two-thirds of the share in Northern 08202.

Western 08202
1% of people above 55 dBA
Northern 08202 sounds about 48% louder than Eastern 08202 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 Cape May County 601 do you need to be?
Cape May County 601 produces an estimated 59 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 2% of 08202 sits under tree canopy (much lighter than most zip codes) and roughly 64% 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.
