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 1,089 North Leg residents, or 29.6%, live above that level. By land area, 47.2% of North Leg is above 55 dBA.
Average noise levels for North Leg residents, grouped by direction from the center of North Leg. Southern North Leg carries the highest population-weighted average; Northern North Leg carries the lowest. Just 28% of residents in Northern North Leg live in blocks above the EPA's 55 dBA threshold, a third of the share in Southern North Leg.

QuietLoud
Southern North Leg sounds about 108% louder than Northern North Leg to the human ear, a 10.6 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 Wylds Rd; do you need to be?
Wylds Rd; produces an estimated 57 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 39% of North Leg sits under tree canopy (much heavier than most neighborhoods) and roughly 35% 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.

Rail Noise
Active freight rail runs through parts of North Leg. For most blocks the rail-only contribution is small. Combined road-plus-rail noise rarely exceeds road noise on its own. The exceptions are the handful of blocks within roughly a quarter mile of the right-of-way during pass-through hours.
Use the Rail toggle on the map above to isolate rail's contribution from road and aviation.
How Noise Is Distributed Across North Leg
The bar chart below shows the share of North Leg residents in each noise band. About 74% of residents live below the EPA's 55 dBA threshold, and roughly 0% live in blocks above 60 dBA. Long-term exposure in that range is linked to elevated stress hormones and cardiovascular risk.
How North Leg Compares
North Leg sits at the quieter end of the spectrum. Below: how North Leg's average outdoor noise and share of residents above the EPA threshold compare with Forrest Hills, Summerville, Highland Park, and West Side.
Average noise level (dBA)
North Leg's 54.2 dBA pop-weighted average is at the quieter end of the spectrum. Georgia as a whole averages 51.0 dBA and the U.S. averages 52.0 dBA. Both are lower than North Leg because most of either area is rural land away from major roads.
Share of residents above 55 dBA
About 29.6% of North Leg residents live in blocks where outdoor levels exceed the EPA's 55 dBA threshold. That's in the middle of its peer group. Measured by land area instead, 47.2% of North Leg's footprint sits above 55 dBA, against a Georgia average of 22.6% and a national average of 28.1%.
What This Means if You're Moving to North Leg
Distance from highways matters more than the neighborhood name. Two homes in the same zip code can differ by 20 dBA if one sits 100 meters from Wylds Rd; and the other 500 meters away. The model captures this at 100-meter resolution, so noise exposure changes block by block.
Tree canopy can help reduce modeled noise exposure. Roughly 39% of North Leg is under tree cover (much heavier than most neighborhoods), and the dominant land cover is low-intensity developed land. Both are measured from federal USDA Forest Service and USGS satellite imagery at 30-meter resolution. Streets with 60% or higher canopy show 3 to 5 dBA lower noise than comparable streets with bare ground or pavement, which is why the per-place decay rate above already accounts for it.
Sources & Methodology
The BestNeighborhood noise model is calibrated against nearly one million federal ground-truth measurements across four states. Road noise is computed from segment-level federal traffic data and propagated outward using physics-based acoustic decay, with attenuation rates that depend on the surrounding land cover.
All inputs are published federal datasets. Block-level noise is computed by combining road, rail, and aviation sound sources in the energy domain, the same physics used in professional environmental noise assessments. Read the full methodology.
