This map shows modeled outdoor noise across Farwell 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 26 Farwell residents, or 10.3%, live above that level. By land area, 9.5% of Farwell is above 55 dBA.

Noise by Part of Farwell
Average noise levels for Farwell residents, grouped by direction from the center of Farwell. Eastern Farwell carries the highest population-weighted average; Southern Farwell carries the lowest. Just 0% of residents in Southern Farwell live in blocks above the EPA's 55 dBA threshold, a fifth of the share in Eastern Farwell.
Eastern Farwell
22% of people above 55 dBA
Northern Farwell
0% of people above 55 dBA
Southern Farwell
0% of people above 55 dBA
Western Farwell
1% of people above 55 dBA
Eastern Farwell sounds about 127% louder than Southern Farwell to the human ear, 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.
Loudest Road Corridors
The model evaluates every road in Farwell using federal traffic counts, posted speeds, heavy-truck ratios, and pavement type. The source level shown is the modeled noise at the road centerline, where it is loudest. Noise drops with distance, faster in vegetated areas and slower over open pavement.
How far back from 16TH Ave do you need to be?
16TH Ave produces an estimated 55 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 3% of Farwell sits under tree canopy (much lighter than most cities) and roughly 12% 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.
How Noise Is Distributed Across Farwell
The bar chart below shows the share of Farwell residents in each noise band. About 92% of residents live below the EPA's 55 dBA threshold, and roughly 0% live in blocks above 60 dBA. Long-term exposure in that range is linked to elevated stress hormones and cardiovascular risk.
How Farwell Compares
Farwell sits at the quieter end of the spectrum. Below: how Farwell's average outdoor noise and share of residents above the EPA threshold compare with Howard City, Nysted, Elba, and Ashton.
Average noise level (dBA)
Farwell's 43.6 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 Farwell because most of either area is rural land away from major roads.
Share of residents above 55 dBA
About 10.3% of Farwell 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, 9.5% of Farwell'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 Farwell
- 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 16TH Ave 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 3% of Farwell is under tree cover (much lighter than most cities), and the dominant land cover is cultivated cropland. 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.
