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 729 St. Regis Park residents, or 41.4%, live above that level. By land area, 35.7% of St. Regis Park is above 55 dBA.
Average noise levels for St. Regis Park residents, grouped by direction from the center of St. Regis Park. Northern St. Regis Park carries the highest population-weighted average; Western St. Regis Park carries the lowest. Just 0% of residents in Western St. Regis Park live in blocks above the EPA's 55 dBA threshold, a fifth of the share in Northern St. Regis Park.

QuietLoud
Northern St. Regis Park sounds about 164% louder than Western St. Regis Park to the human ear, a 14.0 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 far back from I-64 do you need to be?
I-64 produces an estimated 78 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 quiet suburban street at night.

Soft rainfall
Calculated from the model's calibrated attenuation formula. About 23% of St. Regis Park sits under tree canopy (about average for cities) and roughly 26% 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.

Airport Noise
Louisville Muhammad Ali International (SDF) sits southwest of St. Regis Park. 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 St. Regis Park, particularly to the northeast, show no measurable aviation contribution. Use the Aviation toggle on the map above to isolate the airport's footprint.
How Noise Is Distributed Across St. Regis Park
The bar chart below shows the share of St. Regis Park residents in each noise band. About 62% of residents live below the EPA's 55 dBA threshold, and roughly 16% live in blocks above 60 dBA. Long-term exposure in that range is linked to elevated stress hormones and cardiovascular risk.
How St. Regis Park Compares
St. Regis Park sits at the quieter end of the spectrum. Below: how St. Regis Park's average outdoor noise and share of residents above the EPA threshold compare with Hurstbourne Acres, West Buechel, Windy Hills, and Audubon Park.
Average noise level (dBA)
St. Regis Park's 54.5 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 St. Regis Park because most of either area is rural land away from major roads.
Share of residents above 55 dBA
About 41.4% of St. Regis Park 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, 35.7% of St. Regis Park'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 St. Regis Park
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 I-64 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 23% of St. Regis Park is under tree cover (about average for cities), and the dominant land cover is low-density developed open space. 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. Louisville Muhammad Ali International's approach paths concentrate aviation noise to the southwest. Neighborhoods to the northeast 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.
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.
