This map shows modeled outdoor noise across Yost 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 2 Yost residents, or 1.0%, live above that level. By land area, 1.9% of Yost is above 55 dBA.

Noise by Part of Yost
Average noise levels for Yost residents, grouped by direction from the center of Yost. Northern Yost carries the highest population-weighted average; Western Yost carries the lowest. Just 0% of residents in Western Yost live in blocks above the EPA's 55 dBA threshold, a fifth of the share in Northern Yost.
Eastern Yost
2% of people above 55 dBA
Northern Yost
1% of people above 55 dBA
Southern Yost
2% of people above 55 dBA
Western Yost
0% of people above 55 dBA
Northern Yost sounds about 65% louder than Western Yost to the human ear, a 7.2 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 1576-BETTYS Hill do you need to be?
1576-BETTYS Hill produces an estimated 57 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 81% of Yost sits under tree canopy (much heavier than most 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.
