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 1,091 Molholm Two Creeks residents, or 30.7%, live above that level. By land area, 43.4% of Molholm Two Creeks is above 55 dBA.
Average noise levels for Molholm Two Creeks residents, grouped by direction from the center of Molholm Two Creeks. Southern Molholm Two Creeks carries the highest population-weighted average; Central Molholm Two Creeks carries the lowest. Just 14% of residents in Central Molholm Two Creeks live in blocks above the EPA's 55 dBA threshold, a third of the share in Southern Molholm Two Creeks.

QuietLoud
Southern Molholm Two Creeks sounds about 120% louder than Central Molholm Two Creeks to the human ear, a 11.4 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 14TH Av do you need to be?
14TH Av produces an estimated 55 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 Molholm Two Creeks sits under tree canopy (lighter than most neighborhoods) and roughly 44% 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 Molholm Two Creeks. 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 Molholm Two Creeks. 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 Molholm Two Creeks, 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 Molholm Two Creeks
The bar chart below shows the share of Molholm Two Creeks residents in each noise band. About 69% of residents live below the EPA's 55 dBA threshold, and roughly 14% live in blocks above 60 dBA. Long-term exposure in that range is linked to elevated stress hormones and cardiovascular risk.
How Molholm Two Creeks Compares
Molholm Two Creeks sits at the louder end of the spectrum. Below: how Molholm Two Creeks's average outdoor noise and share of residents above the EPA threshold compare with Spivak, Central West Denver, Barths, and Bel Aire.
Average noise level (dBA)
Molholm Two Creeks's 54.4 dBA pop-weighted average is at the louder end of the spectrum. Colorado as a whole averages 51.9 dBA and the U.S. averages 52.0 dBA. Both are lower than Molholm Two Creeks because most of either area is rural land away from major roads.
Share of residents above 55 dBA
About 30.7% of Molholm Two Creeks 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, 43.4% of Molholm Two Creeks'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 Molholm Two Creeks
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 14TH Av 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 Molholm Two Creeks is under tree cover (lighter 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. 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.
