This map shows modeled outdoor noise across 55758 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 32 55758 residents, or 23.2%, live above that level. By land area, 16.6% of 55758 is above 55 dBA.

Noise by Part of 55758
Average noise levels for 55758 residents, grouped by direction from the center of 55758. Southern 55758 carries the highest population-weighted average; Eastern 55758 carries the lowest. Just 0% of residents in Eastern 55758 live in blocks above the EPA's 55 dBA threshold, a fifth of the share in Southern 55758.
Central 55758
29% of people above 55 dBA
Eastern 55758
0% of people above 55 dBA
Southern 55758
10% of people above 55 dBA
Southern 55758 sounds about 175% louder than Eastern 55758 to the human ear, a 14.6 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 67 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 21% of 55758 sits under tree canopy (about average for zip codes) and roughly 33% 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.
