This map shows modeled outdoor noise across 48825 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 0 48825 residents, or 0.0%, live above that level. By land area, 23.5% of 48825 is above 55 dBA.

Noise by Part of 48825
Average noise levels for 48825 residents, grouped by direction from the center of 48825. Eastern 48825 carries the highest population-weighted average; Western 48825 carries the lowest. Just 0% of residents in Western 48825 live in blocks above the EPA's 55 dBA threshold, a fraction of the share in Eastern 48825.

Eastern 48825 sounds about 91% louder than Western 48825 to the human ear, a 9.3 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 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 0% of 48825 sits under tree canopy (much lighter than most zip codes) and roughly 58% 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.
