This map shows modeled outdoor noise across Country Club 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 233 Country Club residents, or 5.9%, live above that level. By land area, 3.1% of Country Club is above 55 dBA.

Noise by Part of Country Club
Average noise levels for Country Club residents, grouped by direction from the center of Country Club. The highest population-weighted average is in southwestern Country Club; the lowest is in southeastern Country Club, where just 2% of residents live in blocks above the EPA's 55 dBA threshold, a fifth of the share in the loudest section.
Southwestern Country Club
15% of people above 55 dBA
Southern Country Club
14% of people above 55 dBA
Northeastern Country Club
2% of people above 55 dBA
Central Country Club
2% of people above 55 dBA
Southeastern Country Club
2% of people above 55 dBA
To the human ear, noise in southwestern Country Club sounds about 95% louder than in southeastern Country Club, a 9.6 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 Noise Is Distributed Across Country Club
The bar chart below shows the share of Country Club residents in each noise band. About 89% 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 Country Club Compares
Country Club sits at the quieter end of the spectrum. Below: how Country Club's average outdoor noise and share of residents above the EPA threshold compare with 40th and A, Hartley, Malone, and Meadowlane.
Average noise level (dBA)
Country Club's 44.4 dBA pop-weighted average is at the quieter end of the spectrum. Nebraska as a whole averages 50.7 dBA and the U.S. averages 52.0 dBA. Both are lower than Country Club because most of either area is rural land away from major roads.
Share of residents above 55 dBA
About 5.9% of Country Club 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, 3.1% of Country Club's footprint sits above 55 dBA, against a Nebraska average of 22.4% and a national average of 28.1%.
What This Means if You're Moving to Country Club
- 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 27TH St 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 27% of Country Club 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.
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.
