This map shows modeled outdoor noise across Starkville 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 57 Starkville residents, or 24.2%, live above that level. By land area, 33.2% of Starkville is above 55 dBA.

Noise by Part of Starkville
Average noise levels for Starkville residents, grouped by direction from the center of Starkville. Northern Starkville carries the highest population-weighted average; Southern Starkville carries the lowest. Just 0% of residents in Southern Starkville live in blocks above the EPA's 55 dBA threshold, a fifth of the share in Northern Starkville.
Eastern Starkville
1% of people above 55 dBA
Northern Starkville
57% of people above 55 dBA
Southern Starkville
0% of people above 55 dBA
Northern Starkville sounds about 482% louder than Southern Starkville to the human ear, a 25.4 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 I-25 do you need to be?
I-25 produces an estimated 73 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 29% of Starkville sits under tree canopy (about average for cities) and roughly 9% 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.
