This map shows modeled outdoor noise across 59020 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 7 59020 residents, or 10.2%, live above that level. By land area, 9.2% of 59020 is above 55 dBA.

Noise by Part of 59020
Average noise levels for 59020 residents, grouped by direction from the center of 59020. Southern 59020 carries the highest population-weighted average; Eastern 59020 carries the lowest. Just 6% of residents in Eastern 59020 live in blocks above the EPA's 55 dBA threshold, a fraction of the share in Southern 59020.
Central 59020
18% of people above 55 dBA
Eastern 59020
6% of people above 55 dBA
Northern 59020
0% of people above 55 dBA
Southern 59020
0% of people above 55 dBA
Western 59020
15% of people above 55 dBA
Southern 59020 sounds about 66% louder than Eastern 59020 to the human ear, a 7.3 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 Daisy Pass Rd do you need to be?
Daisy Pass 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 18% of 59020 sits under tree canopy (about average for zip codes) and roughly 10% 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.
