This map shows modeled outdoor noise across Elm Hall 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 10 Elm Hall residents, or 3.7%, live above that level. By land area, 2.1% of Elm Hall is above 55 dBA.

Noise by Part of Elm Hall
Average noise levels for Elm Hall residents, grouped by direction from the center of Elm Hall. Eastern Elm Hall carries the highest population-weighted average; Western Elm Hall carries the lowest. Just 1% of residents in Western Elm Hall live in blocks above the EPA's 55 dBA threshold, a third of the share in Eastern Elm Hall.

Western Elm Hall

Eastern Elm Hall sounds about 67% louder than Western Elm Hall to the human ear, a 7.4 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 La 1006 do you need to be?
La 1006 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 22% of Elm Hall 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.
