This map shows modeled outdoor noise across 32908 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 2,265 32908 residents, or 19.0%, live above that level. By land area, 21.7% of 32908 is above 55 dBA.

Noise by Part of 32908
Average noise levels for 32908 residents, grouped by direction from the center of 32908. Central 32908 carries the highest population-weighted average; Western 32908 carries the lowest. Just 20% of residents in Western 32908 live in blocks above the EPA's 55 dBA threshold, a third of the share in Central 32908.
Central 32908
74% of people above 55 dBA
Eastern 32908
12% of people above 55 dBA
Northern 32908
18% of people above 55 dBA
Southern 32908
21% of people above 55 dBA
Western 32908
20% of people above 55 dBA
Central 32908 sounds about 55% louder than Western 32908 to the human ear, a 6.3 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 Malabar Rd do you need to be?
Malabar 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 18% of 32908 sits under tree canopy (about average for zip codes) and roughly 20% 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.
