This map shows modeled outdoor noise across Carmel 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 829 Carmel residents, or 14.4%, live above that level. By land area, 22.6% of Carmel is above 55 dBA.

Noise by Part of Carmel
Average noise levels for Carmel residents, grouped by direction from the center of Carmel. The highest population-weighted average is in southwestern Carmel; the lowest is in northern Carmel, where just 11% of residents live in blocks above the EPA's 55 dBA threshold, about half the share in the loudest section.

Quiet office to normal conversation
To the human ear, noise in southwestern Carmel sounds about 73% louder than in northern Carmel, a 7.9 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-79351 do you need to be?
Ns-79351 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 55% of Carmel sits under tree canopy (much heavier than most neighborhoods) and roughly 24% 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 Carmel. 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 Carmel, 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 Carmel
The bar chart below shows the share of Carmel residents in each noise band. About 80% of residents live below the EPA's 55 dBA threshold, and roughly 3% live in blocks above 60 dBA. Long-term exposure in that range is linked to elevated stress hormones and cardiovascular risk.
How Carmel Compares
Carmel sits the lowest among the peer group. Below: how Carmel's average outdoor noise and share of residents above the EPA threshold compare with Park Crossing, Olde Providence South, Barclay Downs, and Johnston-McAlpine.
Average noise level (dBA)
Carmel's 51.4 dBA pop-weighted average is the lowest 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 Carmel because most of either area is rural land away from major roads.
Share of residents above 55 dBA
About 14.4% of Carmel residents live in blocks where outdoor levels exceed the EPA's 55 dBA threshold. That's fewer than any of its peer group. Measured by land area instead, 22.6% of Carmel'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 Carmel
- 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-79351 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 55% of Carmel 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 northwest. Neighborhoods to the southeast of downtown show no measurable contribution from the airport.
