This map shows modeled outdoor noise across Dorneyville 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 909 Dorneyville residents, or 68.7%, live above that level. By land area, 69.3% of Dorneyville is above 55 dBA.

Noise by Part of Dorneyville
Average noise levels for Dorneyville residents, grouped by direction from the center of Dorneyville. Southern Dorneyville carries the highest population-weighted average; Eastern Dorneyville carries the lowest. Just 54% of residents in Eastern Dorneyville live in blocks above the EPA's 55 dBA threshold, about two-thirds of the share in Southern Dorneyville.
Central Dorneyville

Western Dorneyville

Southern Dorneyville sounds about 60% louder than Eastern Dorneyville to the human ear, a 6.8 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 Hamilton BL do you need to be?
Hamilton BL produces an estimated 66 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 37% of Dorneyville sits under tree canopy (about average for cities) and roughly 27% 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.
