This map shows modeled outdoor noise across 12732 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 11 12732 residents, or 1.4%, live above that level. By land area, 2.4% of 12732 is above 55 dBA.

Noise by Part of 12732
Average noise levels for 12732 residents, grouped by direction from the center of 12732. Central 12732 carries the highest population-weighted average; Northern 12732 carries the lowest. Just 1% of residents in Northern 12732 live in blocks above the EPA's 55 dBA threshold, a fraction of the share in Central 12732.

Central 12732 sounds about 111% louder than Northern 12732 to the human ear, a 10.8 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 Cr12 Board Rd do you need to be?
Cr12 Board Rd produces an estimated 57 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 82% of 12732 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.
