This map shows modeled outdoor noise across Sidney Center 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 47 Sidney Center residents, or 4.1%, live above that level. By land area, 3.9% of Sidney Center is above 55 dBA.

Noise by Part of Sidney Center
Average noise levels for Sidney Center residents, grouped by direction from the center of Sidney Center. Southern Sidney Center carries the highest population-weighted average; Western Sidney Center carries the lowest. Just 1% of residents in Western Sidney Center live in blocks above the EPA's 55 dBA threshold, a fifth of the share in Southern Sidney Center.
Eastern Sidney Center
2% of people above 55 dBA
Northern Sidney Center
4% of people above 55 dBA
Southern Sidney Center
7% of people above 55 dBA
Western Sidney Center
1% of people above 55 dBA
Southern Sidney Center sounds about 72% louder than Western Sidney Center to the human ear, a 7.8 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 Sidney Rd do you need to be?
Sidney Rd 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 65% of Sidney Center sits under tree canopy (much heavier than most cities) and roughly 2% 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.
