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 140 Foxfield residents, or 18.6%, live above that level. By land area, 25.1% of Foxfield is above 55 dBA.
Average noise levels for Foxfield residents, grouped by direction from the center of Foxfield. Western Foxfield carries the highest population-weighted average; Southern Foxfield carries the lowest. Just 13% of residents in Southern Foxfield live in blocks above the EPA's 55 dBA threshold, about two-thirds of the share in Western Foxfield.

QuietLoud
Western Foxfield sounds about 80% louder than Southern Foxfield to the human ear, a 8.5 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 do you need to be?
produces an estimated 71 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 2% of Foxfield sits under tree canopy (much lighter than most cities) and roughly 16% 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
Denver International (DEN) sits north of Foxfield. The U.S. Department of Transportation measures aviation noise around this airport directly, 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 75 dBA on the map's Overall layer. Blocks on the opposite side of Foxfield, particularly to the south, show no measurable aviation contribution. Use the Aviation toggle on the map above to isolate the airport's footprint.
How Noise Is Distributed Across Foxfield
The bar chart below shows the share of Foxfield residents in each noise band. About 90% of residents live below the EPA's 55 dBA threshold, and roughly 10% live in blocks above 60 dBA. Long-term exposure in that range is linked to elevated stress hormones and cardiovascular risk.
How Foxfield Compares
Foxfield sits at the quieter end of the spectrum. Below: how Foxfield's average outdoor noise and share of residents above the EPA threshold compare with Hilltop, Bow Mar, North Washington, and Mount Vernon Club Place.
Average noise level (dBA)
Foxfield's 50.0 dBA pop-weighted average is at the quieter end of the spectrum. Colorado as a whole averages 51.9 dBA and the U.S. averages 52.0 dBA. Both are lower than Foxfield because most of either area is rural land away from major roads.
Share of residents above 55 dBA
About 18.6% of Foxfield 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, 25.1% of Foxfield's footprint sits above 55 dBA, against a Colorado average of 25.4% and a national average of 28.1%.
What This Means if You're Moving to Foxfield
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 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 2% of Foxfield is under tree cover (much lighter than most 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. Denver International's approach paths concentrate aviation noise to the north. Neighborhoods to the south 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.
