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 1,742 Central West Denver residents, or 48.4%, live above that level. By land area, 70.9% of Central West Denver is above 55 dBA.
Average noise levels for Central West Denver residents, grouped by direction from the center of Central West Denver. Western Central West Denver carries the highest population-weighted average; Northern Central West Denver carries the lowest. Just 36% of residents in Northern Central West Denver live in blocks above the EPA's 55 dBA threshold, about half the share in Western Central West Denver.

QuietLoud
Western Central West Denver sounds about 119% louder than Northern Central West Denver to the human ear, a 11.3 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.
How far back from US Hwy 6 do you need to be?
US Hwy 6 produces an estimated 72 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 7% of Central West Denver sits under tree canopy (lighter than most neighborhoods) and roughly 55% 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.

Rail Noise
Active freight rail runs through parts of Central West Denver. 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
Denver International (DEN) sits northeast of Central West Denver. 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 Central West Denver, particularly to the southwest, show no measurable aviation contribution. Use the Aviation toggle on the map above to isolate the airport's footprint.
How Noise Is Distributed Across Central West Denver
The bar chart below shows the share of Central West Denver residents in each noise band. About 40% of residents live below the EPA's 55 dBA threshold, and roughly 21% live in blocks above 60 dBA. Long-term exposure in that range is linked to elevated stress hormones and cardiovascular risk.
How Central West Denver Compares
Central West Denver sits at the quieter end of the spectrum. Below: how Central West Denver's average outdoor noise and share of residents above the EPA threshold compare with Molholm Two Creeks, Spivak, Barnum, and Barnum West.
Average noise level (dBA)
Central West Denver's 55.7 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 Central West Denver because most of either area is rural land away from major roads.
Share of residents above 55 dBA
About 48.4% of Central West Denver 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, 70.9% of Central West Denver'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 Central West Denver
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 US Hwy 6 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 7% of Central West Denver is under tree cover (lighter than most neighborhoods), and the dominant land cover is medium-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. Denver International's approach paths concentrate aviation noise to the northeast. Neighborhoods to the southwest 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.
