This map shows modeled outdoor noise across Golden Triangle at 100-meter resolution, combining road, aviation, and rail sources. Green areas measure below 45 dBA. Orange and red exceed the EPA's 55 dBA outdoor threshold linked to long-term health effects. Use the layer toggles to view each source on its own or all together.

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 1,983 Golden Triangle residents, or 70.8%, live above that level. By land area, 80.6% of Golden Triangle is above 55 dBA.

Noise by Part of Golden Triangle
Average noise levels for Golden Triangle residents, grouped by direction from the center of Golden Triangle. The highest population-weighted average is in central Golden Triangle; the lowest is in northern Golden Triangle, where just 83% of residents live in blocks above the EPA's 55 dBA threshold, roughly the same as the share in the loudest section.

To the human ear, noise in central Golden Triangle sounds about 12% louder than in northern Golden Triangle, a 1.6 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 74 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 0% of Golden Triangle sits under tree canopy (much lighter than most neighborhoods) and roughly 82% 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 northeast of Golden Triangle. 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 Golden Triangle, 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 Golden Triangle
The bar chart below shows the share of Golden Triangle residents in each noise band. About 20% of residents live below the EPA's 55 dBA threshold, and roughly 63% live in blocks above 60 dBA. Long-term exposure in that range is linked to elevated stress hormones and cardiovascular risk.
How Golden Triangle Compares
Golden Triangle sits the highest among the peer group. Below: how Golden Triangle's average outdoor noise and share of residents above the EPA threshold compare with Skyland, Valverde, Globeville, and Clayton.
Average noise level (dBA)
Golden Triangle's 60.8 dBA pop-weighted average is the highest among the peer group. Colorado as a whole averages 51.9 dBA and the U.S. averages 52.0 dBA. Both are lower than Golden Triangle because most of either area is rural land away from major roads.
Share of residents above 55 dBA
About 70.8% of Golden Triangle 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, 80.6% of Golden Triangle'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 Golden Triangle
- 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 0% of Golden Triangle is under tree cover (much lighter than most neighborhoods), and the dominant land cover is high-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.
