This map shows modeled outdoor noise across 44302 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 1,637 44302 residents, or 40.9%, live above that level. By land area, 46.1% of 44302 is above 55 dBA.

Noise by Part of 44302
Average noise levels for 44302 residents, grouped by direction from the center of 44302. The highest population-weighted average is in southeastern 44302; the lowest is in central 44302, where just 37% of residents live in blocks above the EPA's 55 dBA threshold, three-quarters of the share in the loudest section.
Southeastern 44302
45% of people above 55 dBA
Northwestern 44302
40% of people above 55 dBA
Western 44302
44% of people above 55 dBA
Central 44302
37% of people above 55 dBA
To the human ear, noise in southeastern 44302 sounds about 20% louder than in central 44302, a 2.6 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 W Exchange St do you need to be?
W Exchange St 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 29% of 44302 sits under tree canopy (about average for zip codes) and roughly 41% 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.
