This map shows modeled outdoor noise across Mary Esther 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 3,540 Mary Esther residents, or 30.4%, live above that level. By land area, 32.3% of Mary Esther is above 55 dBA.

Noise by Part of Mary Esther
Average noise levels for Mary Esther residents, grouped by direction from the center of Mary Esther. The highest population-weighted average is in central Mary Esther; the lowest is in the Wynnehaven Beach Estates area (western Mary Esther), where just 17% of residents live in blocks above the EPA's 55 dBA threshold, roughly the same as the share in the loudest section.
Central Mary Esther
19% of people above 55 dBA
Eastern Mary Esther
25% of people above 55 dBA
Wynnehaven Beach Estates
17% of people above 55 dBA
To the human ear, noise in central Mary Esther sounds about 18% louder than in the Wynnehaven Beach Estates area (western Mary Esther), a 2.4 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 US-98 do you need to be?
US-98 produces an estimated 67 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 20% of Mary Esther sits under tree canopy (lighter than most cities) and roughly 40% 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.
