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 56 28745 residents, or 13.1%, live above that level. By land area, 15.5% of 28745 is above 55 dBA.
Average noise levels for 28745 residents, grouped by direction from the center of 28745. Eastern 28745 carries the highest population-weighted average; Northern 28745 carries the lowest. Just 0% of residents in Northern 28745 live in blocks above the EPA's 55 dBA threshold, a fifth of the share in Eastern 28745.

QuietLoud
Eastern 28745 sounds about 323% louder than Northern 28745 to the human ear, a 20.8 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 SR-1376 do you need to be?
SR-1376 produces an estimated 56 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 45% of 28745 sits under tree canopy (heavier than most zip codes) and roughly 17% 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 28745. 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.
How Noise Is Distributed Across 28745
The bar chart below shows the share of 28745 residents in each noise band. About 76% of residents live below the EPA's 55 dBA threshold, and roughly 1% live in blocks above 60 dBA. Long-term exposure in that range is linked to elevated stress hormones and cardiovascular risk.
How 28745 Compares
28745 sits the highest among the peer group. Below: how 28745's average outdoor noise and share of residents above the EPA threshold compare with 28708, 28775, 28718, and 28702.
Average noise level (dBA)
28745's 48.7 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 28745 because most of either area is rural land away from major roads.
Share of residents above 55 dBA
About 13.1% of 28745 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, 15.5% of 28745'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 28745
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 SR-1376 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 28745 is under tree cover (heavier than most zip codes), 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.
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.
