This map shows modeled outdoor noise across 13158 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 38 13158 residents, or 2.4%, live above that level. By land area, 2.6% of 13158 is above 55 dBA.

Noise by Part of 13158
Average noise levels for 13158 residents, grouped by direction from the center of 13158. Central 13158 carries the highest population-weighted average; Northern 13158 carries the lowest. Just 3% of residents in Northern 13158 live in blocks above the EPA's 55 dBA threshold, about two-thirds of the share in Central 13158.

Central 13158 sounds about 53% louder than Northern 13158 to the human ear, a 6.1 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 61 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 50% of 13158 sits under tree canopy (much heavier than most zip codes) and roughly 0% 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.
