This map shows modeled outdoor noise across Oakhurst 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 1,206 Oakhurst residents, or 41.0%, live above that level. By land area, 54.2% of Oakhurst is above 55 dBA.

Noise by Part of Oakhurst
Average noise levels for Oakhurst residents, grouped by direction from the center of Oakhurst. The highest population-weighted average is in northwestern Oakhurst; the lowest is in southern Oakhurst, where just 28% of residents live in blocks above the EPA's 55 dBA threshold, about two-thirds of the share in the loudest section.

Central Oakhurst

Southern Oakhurst
58.2 dBA · Loud
Normal conversation an arm’s length away
To the human ear, noise in northwestern Oakhurst sounds about 18% louder than in southern Oakhurst, a 2.4 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 do you need to be?
produces an estimated 77 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 quiet suburban street at night.

Soft rainfall
Calculated from the model's calibrated attenuation formula. About 45% of Oakhurst sits under tree canopy (much heavier than most neighborhoods) and roughly 29% 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 Oakhurst. 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.
Airport Noise
Charlotte/Douglas International (CLT) sits west of Oakhurst. 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 Oakhurst, 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 Oakhurst
The bar chart below shows the share of Oakhurst residents in each noise band. About 44% of residents live below the EPA's 55 dBA threshold, and roughly 5% live in blocks above 60 dBA. Long-term exposure in that range is linked to elevated stress hormones and cardiovascular risk.
How Oakhurst Compares
Oakhurst sits the highest among the peer group. Below: how Oakhurst's average outdoor noise and share of residents above the EPA threshold compare with grier-heights-charlotte-nc, Wendover-Sedgewood, Plaza-Shamrock, and belmont-charlotte-nc.
Average noise level (dBA)
Oakhurst's 55.7 dBA pop-weighted average is the highest among the peer group. North Carolina as a whole averages 49.7 dBA and the U.S. averages 52.0 dBA. Both are lower than Oakhurst because most of either area is rural land away from major roads.
Share of residents above 55 dBA
About 41.0% of Oakhurst 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, 54.2% of Oakhurst'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 Oakhurst
- 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 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 45% of Oakhurst is under tree cover (much heavier than most neighborhoods), and the dominant land cover is low-density developed open space. 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.
