This map shows modeled outdoor noise across Milo 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 16 Milo residents, or 4.8%, live above that level. By land area, 10.0% of Milo is above 55 dBA.

Noise by Part of Milo
Average noise levels for Milo residents, grouped by direction from the center of Milo. Central Milo carries the highest population-weighted average; Northern Milo carries the lowest. Just 0% of residents in Northern Milo live in blocks above the EPA's 55 dBA threshold, a fifth of the share in Central Milo.
Central Milo
12% of people above 55 dBA
Eastern Milo
5% of people above 55 dBA
Northern Milo
0% of people above 55 dBA
Southern Milo
10% of people above 55 dBA
Western Milo
0% of people above 55 dBA
Central Milo sounds about 236% louder than Northern Milo to the human ear, a 17.5 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 Ky-645 do you need to be?
Ky-645 produces an estimated 60 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 84% of Milo 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.
