This map shows modeled outdoor noise across Womack Hill 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 Womack Hill residents, or 0.2%, live above that level. By land area, 0.2% of Womack Hill is above 55 dBA.

Noise by Part of Womack Hill
Average noise levels for Womack Hill residents, grouped by direction from the center of Womack Hill. Southern Womack Hill carries the highest population-weighted average; Western Womack Hill carries the lowest. Just 0% of residents in Western Womack Hill live in blocks above the EPA's 55 dBA threshold, a fifth of the share in Southern Womack Hill.
Eastern Womack Hill
0% of people above 55 dBA
Northern Womack Hill
0% of people above 55 dBA
Southern Womack Hill
0% of people above 55 dBA
Western Womack Hill
0% of people above 55 dBA
Southern Womack Hill sounds about 32% louder than Western Womack Hill to the human ear, a 4.0 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 Refuge do you need to be?
Refuge produces an estimated 55 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 71% of Womack Hill sits under tree canopy (much heavier than most cities) 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.
