This map shows modeled outdoor noise across Old Naples 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 2,676 Old Naples residents, or 67.0%, live above that level. By land area, 74.8% of Old Naples is above 55 dBA.

Noise by Part of Old Naples
Average noise levels for Old Naples residents, grouped by direction from the center of Old Naples. The highest population-weighted average is in northeastern Old Naples; the lowest is in western Old Naples, where just 52% of residents live in blocks above the EPA's 55 dBA threshold, roughly the same as the share in the loudest section.
Northeastern Old Naples
51% of people above 55 dBA
Central Old Naples
68% of people above 55 dBA
Northwestern Old Naples
55% of people above 55 dBA
Southern Old Naples
60% of people above 55 dBA
Western Old Naples
52% of people above 55 dBA
To the human ear, noise in northeastern Old Naples sounds about 25% louder than in western Old Naples, a 3.2 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 Tamiami Trl do you need to be?
Tamiami Trl produces an estimated 69 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 13% of Old Naples sits under tree canopy (about average for neighborhoods) and roughly 51% 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.
