This map shows modeled outdoor noise across Atlantic Beaches 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 4,073 Atlantic Beaches residents, or 35.1%, live above that level. By land area, 44.2% of Atlantic Beaches is above 55 dBA.

Noise by Part of Atlantic Beaches
Average noise levels for Atlantic Beaches residents, grouped by direction from the center of Atlantic Beaches. The highest population-weighted average is in southern Atlantic Beaches; the lowest is in northeastern Atlantic Beaches, where just 13% of residents live in blocks above the EPA's 55 dBA threshold, about half the share in the loudest section.
Southern Atlantic Beaches
32% of people above 55 dBA
Southwestern Atlantic Beaches
32% of people above 55 dBA
Southeastern Atlantic Beaches
26% of people above 55 dBA
Eastern Atlantic Beaches
16% of people above 55 dBA
Northeastern Atlantic Beaches
13% of people above 55 dBA
To the human ear, noise in southern Atlantic Beaches sounds about 77% louder than in northeastern Atlantic Beaches, a 8.2 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 Mayport Rd do you need to be?
Mayport 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 24% of Atlantic Beaches sits under tree canopy (heavier than most neighborhoods) and roughly 39% 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.
