Noise Levels in Idle Hour, Lexington, KY | Find Quiet Neighborhoods With Our Sound Map

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 3,761 Idle Hour residents, or 33.4%, live above that level. By land area, 42.7% of Idle Hour is above 55 dBA.

Noise by Part of Idle Hour

Average noise levels for Idle Hour residents, grouped by direction from the center of Idle Hour. The highest population-weighted average is in western Idle Hour; the lowest is in northeastern Idle Hour, where just 26% of residents live in blocks above the EPA's 55 dBA threshold, about two-thirds of the share in the loudest section.

To the human ear, noise in western Idle Hour sounds about 77% louder than in northeastern Idle Hour, a 8.2 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.

Airport Noise

Blue Grass (LEX) sits west of Idle Hour. 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 Idle Hour, 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 Idle Hour

The bar chart below shows the share of Idle Hour residents in each noise band. About 53% of residents live below the EPA's 55 dBA threshold, and roughly 19% live in blocks above 60 dBA. Long-term exposure in that range is linked to elevated stress hormones and cardiovascular risk.

How Idle Hour Compares

Idle Hour sits the highest among the peer group. Below: how Idle Hour's average outdoor noise and share of residents above the EPA threshold compare with Southeastern Hills, Indian Hills-Stonewall Estates-Monticello, Reservorir, and Liberty Area.

Average noise level (dBA)

Idle Hour's 55.5 dBA pop-weighted average is the highest among the peer group. Kentucky as a whole averages 50.5 dBA and the U.S. averages 52.0 dBA. Both are lower than Idle Hour because most of either area is rural land away from major roads.

Share of residents above 55 dBA

About 33.4% of Idle Hour 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, 42.7% of Idle Hour'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 Idle Hour

• 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 State Hwy 4 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 16% of Idle Hour is under tree cover (about average for 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.
