This map shows modeled outdoor noise across 72636 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 3 72636 residents, or 5.1%, live above that level. By land area, 14.5% of 72636 is above 55 dBA.

Noise by Part of 72636
Average noise levels for 72636 residents, grouped by direction from the center of 72636. Southern 72636 carries the highest population-weighted average; Central 72636 carries the lowest. Just 0% of residents in Central 72636 live in blocks above the EPA's 55 dBA threshold, a fifth of the share in Southern 72636.
Central 72636
0% of people above 55 dBA
Northern 72636
4% of people above 55 dBA
Southern 72636
10% of people above 55 dBA
Western 72636
4% of people above 55 dBA
Southern 72636 sounds about 49% louder than Central 72636 to the human ear, a 5.8 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 Longbottomrd do you need to be?
Longbottomrd 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 65% of 72636 sits under tree canopy (much heavier than most zip codes) and roughly 1% 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.
