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 1,062 Starmount Forest-Charlotte residents, or 16.1%, live above that level. By land area, 26.7% of Starmount Forest-Charlotte is above 55 dBA.

Quiet office
To the human ear, noise in northern Starmount Forest-Charlotte sounds about 127% louder than in central Starmount Forest-Charlotte, a 11.8 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 do you need to be?
produces an estimated 82 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 office.

Soft rainfall
Calculated from the model's calibrated attenuation formula. About 31% of Starmount Forest-Charlotte sits under tree canopy (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.

Rail Noise
Active freight rail runs through parts of Starmount Forest-Charlotte. 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 northwest of Starmount Forest-Charlotte. 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 Starmount Forest-Charlotte, 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 Starmount Forest-Charlotte
The bar chart below shows the share of Starmount Forest-Charlotte residents in each noise band. About 57% of residents live below the EPA's 55 dBA threshold, and roughly 7% live in blocks above 60 dBA. Long-term exposure in that range is linked to elevated stress hormones and cardiovascular risk.
How Starmount Forest-Charlotte Compares
Starmount Forest-Charlotte sits the lowest among the peer group. Below: how Starmount Forest-Charlotte's average outdoor noise and share of residents above the EPA threshold compare with Beverly Woods, Park Crossing, Foxcroft, and Olde Whitehall.
Average noise level (dBA)
Starmount Forest-Charlotte's 50.5 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 Starmount Forest-Charlotte because most of either area is rural land away from major roads.
Share of residents above 55 dBA
About 16.1% of Starmount Forest-Charlotte 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, 26.7% of Starmount Forest-Charlotte'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 Starmount Forest-Charlotte
- 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 31% of Starmount Forest-Charlotte is under tree cover (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.
- 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.
