This map shows modeled outdoor noise across Fairway-Liberty Heights 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 1,498 Fairway-Liberty Heights residents, or 29.3%, live above that level. By land area, 32.2% of Fairway-Liberty Heights is above 55 dBA.

Noise by Part of Fairway-Liberty Heights
Average noise levels for Fairway-Liberty Heights residents, grouped by direction from the center of Fairway-Liberty Heights. The highest population-weighted average is in northwestern Fairway-Liberty Heights; the lowest is in southern Fairway-Liberty Heights, where just 33% of residents live in blocks above the EPA's 55 dBA threshold, about two-thirds of the share in the loudest section.
Northwestern Fairway-Liberty Heights
50% of people above 55 dBA
Western Fairway-Liberty Heights
47% of people above 55 dBA
Northeastern Fairway-Liberty Heights
28% of people above 55 dBA
Southwestern Fairway-Liberty Heights
35% of people above 55 dBA
Southern Fairway-Liberty Heights
33% of people above 55 dBA
To the human ear, noise in northwestern Fairway-Liberty Heights sounds about 26% louder than in southern Fairway-Liberty Heights, a 3.3 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.
Rail Noise
Active freight rail runs through parts of Fairway-Liberty Heights. 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.
Airport Noise
Blue Grass (LEX) sits west of Fairway-Liberty Heights. The U.S. Department of Transportation models aviation noise around this airport from federal traffic data, 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 55 dBA on the map's Overall layer. Blocks on the opposite side of Fairway-Liberty Heights, particularly to the east, show no measurable aviation contribution. Use the Aviation toggle on the map above to isolate the airport's footprint.
How Noise Is Distributed Across Fairway-Liberty Heights
The bar chart below shows the share of Fairway-Liberty Heights residents in each noise band. About 71% of residents live below the EPA's 55 dBA threshold, and roughly 5% live in blocks above 60 dBA. Long-term exposure in that range is linked to elevated stress hormones and cardiovascular risk.
How Fairway-Liberty Heights Compares
Fairway-Liberty Heights sits at the quieter end of the spectrum. Below: how Fairway-Liberty Heights's average outdoor noise and share of residents above the EPA threshold compare with Downtown Lexington, Kenawood-Rockwood, Duncan Park, and Chevy Chase-Ashland Park.
Average noise level (dBA)
Fairway-Liberty Heights's 53.8 dBA pop-weighted average is at the quieter end of the spectrum. Kentucky as a whole averages 50.5 dBA and the U.S. averages 52.0 dBA. Both are lower than Fairway-Liberty Heights because most of either area is rural land away from major roads.
Share of residents above 55 dBA
About 29.3% of Fairway-Liberty Heights 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, 32.2% of Fairway-Liberty Heights's footprint sits above 55 dBA, against a Kentucky average of 23.2% and a national average of 28.1%.
What This Means if You're Moving to Fairway-Liberty Heights
- 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 Liberty Rd 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 19% of Fairway-Liberty Heights 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.
- Airport noise is directional. Blue Grass's approach paths concentrate aviation noise to the west. Neighborhoods to the east of downtown show no measurable contribution from the airport.
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.
