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 811 Seven Eagles residents, or 20.7%, live above that level. By land area, 28.9% of Seven Eagles is above 55 dBA.

Noise by Part of Seven Eagles
Average noise levels for Seven Eagles residents, grouped by direction from the center of Seven Eagles. The highest population-weighted average is in southern Seven Eagles; the lowest is in northern Seven Eagles, where just 6% of residents live in blocks above the EPA's 55 dBA threshold, a third of the share in the loudest section.

To the human ear, noise in southern Seven Eagles sounds about 30% louder than in northern Seven Eagles, a 3.8 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 Ns-914 do you need to be?
Ns-914 produces an estimated 65 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 31% of Seven Eagles sits under tree canopy (heavier than most neighborhoods) and roughly 43% 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.

Airport Noise
Charlotte/Douglas International (CLT) sits northwest of Seven Eagles. The U.S. Department of Transportation measures aviation noise around this airport directly, and the model uses those federal measurements rather than synthetic predictions.
Blocks under the approach and departure paths carry combined road-plus-aviation noise, with some exceeding 75 dBA on the map's Overall layer. Blocks on the opposite side of Seven Eagles, particularly to the southeast, show no measurable aviation contribution. Use the Aviation toggle on the map above to isolate the airport's footprint.
How Noise Is Distributed Across Seven Eagles
The bar chart below shows the share of Seven Eagles residents in each noise band. About 87% of residents live below the EPA's 55 dBA threshold, and roughly 1% live in blocks above 60 dBA. Long-term exposure in that range is linked to elevated stress hormones and cardiovascular risk.
How Seven Eagles Compares
Seven Eagles sits at the quieter end of the spectrum. Below: how Seven Eagles's average outdoor noise and share of residents above the EPA threshold compare with Rain Tree, Closeburn-Glenkirk, Quail Hollow, and Olde Providence North.
Average noise level (dBA)
Seven Eagles's 51.4 dBA pop-weighted average is at the quieter end of the spectrum. North Carolina as a whole averages 49.7 dBA and the U.S. averages 52.0 dBA. Both are lower than Seven Eagles because most of either area is rural land away from major roads.
Share of residents above 55 dBA
About 20.7% of Seven Eagles 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, 28.9% of Seven Eagles's footprint sits above 55 dBA, against a North Carolina average of 22.6% and a national average of 28.1%.
What This Means if You're Moving to Seven Eagles
- 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 Ns-914 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 31% of Seven Eagles is under tree cover (heavier than most neighborhoods), and the dominant land cover is medium-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.
- Airport noise is directional. Charlotte/Douglas International's approach paths concentrate aviation noise to the northwest. Neighborhoods to the southeast of downtown show no measurable contribution from the airport.
