This map shows modeled outdoor noise across Oilville 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 63 Oilville residents, or 8.8%, live above that level. By land area, 23.7% of Oilville is above 55 dBA.

Noise by Part of Oilville
Average noise levels for Oilville residents, grouped by direction from the center of Oilville. Northern Oilville carries the highest population-weighted average; Western Oilville carries the lowest. Just 2% of residents in Western Oilville live in blocks above the EPA's 55 dBA threshold, a fifth of the share in Northern Oilville.
Central Oilville
12% of people above 55 dBA
Eastern Oilville
12% of people above 55 dBA
Northern Oilville
25% of people above 55 dBA
Southern Oilville
3% of people above 55 dBA
Western Oilville
2% of people above 55 dBA
Northern Oilville sounds about 320% louder than Western Oilville to the human ear, a 20.7 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 I-64 do you need to be?
I-64 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 quiet suburban street at night.
Calculated from the model's calibrated attenuation formula. About 58% of Oilville sits under tree canopy (heavier than most cities) and roughly 6% 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.
