This map shows modeled outdoor noise across Wake Forest University 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 698 Wake Forest University residents, or 16.8%, live above that level. By land area, 24.5% of Wake Forest University is above 55 dBA.

How Noise Is Distributed Across Wake Forest University
The bar chart below shows the share of Wake Forest University residents in each noise band. About 97% of residents live below the EPA's 55 dBA threshold, and roughly 2% live in blocks above 60 dBA. Long-term exposure in that range is linked to elevated stress hormones and cardiovascular risk.
How Wake Forest University Compares
Wake Forest University sits the lowest among the peer group. Below: how Wake Forest University's average outdoor noise and share of residents above the EPA threshold compare with Ardmore, brookwood-winston-salem-nc, Konnoak, and East Winston.
Average noise level (dBA)
Wake Forest University's 50.1 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 Wake Forest University because most of either area is rural land away from major roads.
Share of residents above 55 dBA
About 16.8% of Wake Forest University 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, 24.5% of Wake Forest University'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 Wake Forest University
- 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 18% of Wake Forest University is under tree cover (about average for neighborhoods), and the dominant land cover is medium-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.
Federal datasets used:
FHWA Highway Performance Monitoring System: road geometry, traffic counts, lane configuration
U.S. DoT Bureau of Transportation Statistics National Transportation Noise Map: aviation and rail noise, road calibration ground truth
USGS / MRLC National Land Cover Database: land cover and impervious surface coverage
USDA Forest Service Tree Canopy Cover: vegetation density for sound propagation
U.S. Census Bureau TIGER/Line: block-level geography and population
U.S. EPA Levels Document: 55 dBA outdoor reference level
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.
