This map shows modeled outdoor noise across Carls Corner 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 22 Carls Corner residents, or 11.7%, live above that level. By land area, 23.1% of Carls Corner is above 55 dBA.

Noise by Part of Carls Corner
Average noise levels for Carls Corner residents, grouped by direction from the center of Carls Corner. Eastern Carls Corner carries the highest population-weighted average; Southern Carls Corner carries the lowest. Just 27% of residents in Southern Carls Corner live in blocks above the EPA's 55 dBA threshold, roughly the same as the share in Eastern Carls Corner.

Eastern Carls Corner sounds about 169% louder than Southern Carls Corner to the human ear, a 14.3 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 35E do you need to be?
35E produces an estimated 76 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 3% of Carls Corner sits under tree canopy (much lighter than most cities) 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.
