This map shows modeled outdoor noise across Grove Park 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 4 Grove Park residents, or 0.6%, live above that level. By land area, 5.0% of Grove Park is above 55 dBA.

Noise by Part of Grove Park
Average noise levels for Grove Park residents, grouped by direction from the center of Grove Park. Western Grove Park carries the highest population-weighted average; Southern Grove Park carries the lowest. Just 0% of residents in Southern Grove Park live in blocks above the EPA's 55 dBA threshold, a fifth of the share in Western Grove Park.
Eastern Grove Park
0% of people above 55 dBA
Northern Grove Park
0% of people above 55 dBA
Southern Grove Park
0% of people above 55 dBA
Western Grove Park
2% of people above 55 dBA
Western Grove Park sounds about 40% louder than Southern Grove Park to the human ear, a 4.9 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 SE Hawthorne Rd do you need to be?
SE Hawthorne Rd produces an estimated 64 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 64% of Grove Park sits under tree canopy (much heavier than most cities) and roughly 0% 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.
