This map shows modeled outdoor noise across Slater Park 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 2,198 Slater Park residents, or 55.0%, live above that level. By land area, 60.7% of Slater Park is above 55 dBA.

Noise by Part of Slater Park
Average noise levels for Slater Park residents, grouped by direction from the center of Slater Park. The highest population-weighted average is in southern Slater Park; the lowest is in western Slater Park, where just 67% of residents live in blocks above the EPA's 55 dBA threshold, roughly the same as the share in the loudest section.

Highway traffic 50 ft away
To the human ear, noise in southern Slater Park sounds about 9% louder than in western Slater Park, a 1.2 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 I-77 do you need to be?
I-77 produces an estimated 79 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 60% of Slater Park sits under tree canopy (much heavier than most neighborhoods) and roughly 18% 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 southwest of Slater 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 45 dBA on the map's Overall layer. Blocks on the opposite side of Slater Park, particularly to the northeast, show no measurable aviation contribution. Use the Aviation toggle on the map above to isolate the airport's footprint.
How Noise Is Distributed Across Slater Park
The bar chart below shows the share of Slater Park residents in each noise band. About 30% of residents live below the EPA's 55 dBA threshold, and roughly 33% live in blocks above 60 dBA. Long-term exposure in that range is linked to elevated stress hormones and cardiovascular risk.
How Slater Park Compares
Slater Park sits at the louder end of the spectrum. Below: how Slater Park's average outdoor noise and share of residents above the EPA threshold compare with Beatties Ford-Trinity, Rockwell Park-Hemphill Heights, North Charlotte, and Westchester.
Average noise level (dBA)
Slater Park's 58.9 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 Slater Park because most of either area is rural land away from major roads.
Share of residents above 55 dBA
About 55.0% of Slater Park residents live in blocks where outdoor levels exceed the EPA's 55 dBA threshold. That's more than any of its peer group. Measured by land area instead, 60.7% of Slater 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 Slater 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 I-77 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 60% of Slater Park 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 southwest. Neighborhoods to the northeast of downtown show no measurable contribution from the airport.
