This map shows modeled outdoor noise across Flying Horse 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 852 Flying Horse residents, or 23.5%, live above that level. By land area, 30.4% of Flying Horse is above 55 dBA.

Noise by Part of Flying Horse
Average noise levels for Flying Horse residents, grouped by direction from the center of Flying Horse. The highest population-weighted average is in southern Flying Horse; the lowest is in northwestern Flying Horse, where just 19% of residents live in blocks above the EPA's 55 dBA threshold, three-quarters of the share in the loudest section.
Southern Flying Horse
24% of people above 55 dBA
Northeastern Flying Horse
19% of people above 55 dBA
Northern Flying Horse
19% of people above 55 dBA
Northwestern Flying Horse
19% of people above 55 dBA
To the human ear, noise in southern Flying Horse sounds about 9% louder than in northwestern Flying Horse, a 1.2 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 Old North Gate Rd do you need to be?
Old North Gate Rd produces an estimated 56 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 2% of Flying Horse sits under tree canopy (much lighter than most neighborhoods) and roughly 14% 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.
