This map shows modeled outdoor noise across 49963 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 88 49963 residents, or 11.8%, live above that level. By land area, 11.5% of 49963 is above 55 dBA.

Noise by Part of 49963
Average noise levels for 49963 residents, grouped by direction from the center of 49963. Central 49963 carries the highest population-weighted average; Southern 49963 carries the lowest. Just 0% of residents in Southern 49963 live in blocks above the EPA's 55 dBA threshold, a fifth of the share in Central 49963.

Central 49963 sounds about 123% louder than Southern 49963 to the human ear, a 11.6 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 Baltic Onkalos Corner Rd do you need to be?
Baltic Onkalos Corner Rd produces an estimated 51 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 20% of 49963 sits under tree canopy (about average for zip codes) and roughly 26% 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.
