This map shows modeled outdoor noise across Clarks Green 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 550 Clarks Green residents, or 38.7%, live above that level. By land area, 37.8% of Clarks Green is above 55 dBA.

Noise by Part of Clarks Green
Average noise levels for Clarks Green residents, grouped by direction from the center of Clarks Green. Western Clarks Green carries the highest population-weighted average; Northern Clarks Green carries the lowest. Just 24% of residents in Northern Clarks Green live in blocks above the EPA's 55 dBA threshold, three-quarters of the share in Western Clarks Green.

Western Clarks Green sounds about 14% louder than Northern Clarks Green to the human ear, a 1.9 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 do you need to be?
produces an estimated 64 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 33% of Clarks Green sits under tree canopy (about average for cities) and roughly 20% 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.
