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 2,153 Eastway-Sheffield Park residents, or 38.4%, live above that level. By land area, 57.7% of Eastway-Sheffield Park is above 55 dBA.
Average noise levels for Eastway-Sheffield Park residents, grouped by direction from the center of Eastway-Sheffield Park. Eastern Eastway-Sheffield Park carries the highest population-weighted average; Northern Eastway-Sheffield Park carries the lowest. Just 0% of residents in Northern Eastway-Sheffield Park live in blocks above the EPA's 55 dBA threshold, a fifth of the share in Eastern Eastway-Sheffield Park.

QuietLoud
Eastern Eastway-Sheffield Park sounds about 193% louder than Northern Eastway-Sheffield Park to the human ear, a 15.5 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-923 do you need to be?
Ns-923 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 33% of Eastway-Sheffield Park sits under tree canopy (much heavier than most neighborhoods) and roughly 42% 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 west of Eastway-Sheffield Park. 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 Eastway-Sheffield Park, particularly to the east, show no measurable aviation contribution. Use the Aviation toggle on the map above to isolate the airport's footprint.
How Noise Is Distributed Across Eastway-Sheffield Park
The bar chart below shows the share of Eastway-Sheffield Park residents in each noise band. About 46% of residents live below the EPA's 55 dBA threshold, and roughly 30% live in blocks above 60 dBA. Long-term exposure in that range is linked to elevated stress hormones and cardiovascular risk.
How Eastway-Sheffield Park Compares
Eastway-Sheffield Park sits at the louder end of the spectrum. Below: how Eastway-Sheffield Park's average outdoor noise and share of residents above the EPA threshold compare with Eastland-Wilora Lake, Marlwood, Hickory Grove, and Elizabeth.
Average noise level (dBA)
Eastway-Sheffield Park's 55.7 dBA pop-weighted average is at the louder 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 Eastway-Sheffield Park because most of either area is rural land away from major roads.
Share of residents above 55 dBA
About 38.4% of Eastway-Sheffield Park 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, 57.7% of Eastway-Sheffield Park'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 Eastway-Sheffield Park
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-923 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 33% of Eastway-Sheffield Park is under tree cover (much 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 west. Neighborhoods to the east of downtown show no measurable contribution from the airport.
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.
