This map shows modeled outdoor noise across Summerfield 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 4 Summerfield residents, or 2.7%, live above that level. By land area, 2.7% of Summerfield is above 55 dBA.

Noise by Part of Summerfield
Average noise levels for Summerfield residents, grouped by direction from the center of Summerfield. Southern Summerfield carries the highest population-weighted average; Western Summerfield carries the lowest. Just 0% of residents in Western Summerfield live in blocks above the EPA's 55 dBA threshold, a fifth of the share in Southern Summerfield.
Eastern Summerfield
1% of people above 55 dBA
Southern Summerfield
7% of people above 55 dBA
Western Summerfield
0% of people above 55 dBA
Southern Summerfield sounds about 199% louder than Western Summerfield to the human ear, a 15.8 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 Route 519 do you need to be?
Route 519 produces an estimated 58 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 23% of Summerfield sits under tree canopy (about average for 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.
