This map shows modeled outdoor noise across Florida 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 262 Florida residents, or 5.6%, live above that level. By land area, 10.3% of Florida is above 55 dBA.

Noise by Part of Florida
Average noise levels for Florida residents, grouped by direction from the center of Florida. Central Florida carries the highest population-weighted average; Northern Florida carries the lowest. Just 5% of residents in Northern Florida live in blocks above the EPA's 55 dBA threshold, three-quarters of the share in Central Florida.
Central Florida
6% of people above 55 dBA
Eastern Florida
8% of people above 55 dBA
Northern Florida
5% of people above 55 dBA
Southern Florida
3% of people above 55 dBA
Western Florida
6% of people above 55 dBA
Central Florida sounds about 27% louder than Northern Florida to the human ear, a 3.5 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 Union Cnrs Rd do you need to be?
Union Cnrs Rd produces an estimated 59 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 34% of Florida sits under tree canopy (about average for cities) and roughly 15% 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.
