Noise Levels in Security-Widefield, CO | Find Quiet Neighborhoods With Our Sound Map

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 12,890 Security-Widefield residents, or 37.8%, live above that level. By land area, 42.8% of Security-Widefield is above 55 dBA.

Noise by Part of Security-Widefield

Average noise levels for Security-Widefield residents, grouped by direction from the center of Security-Widefield. Central Security-Widefield carries the highest population-weighted average; Northern Security-Widefield carries the lowest. Just 41% of residents in Northern Security-Widefield live in blocks above the EPA's 55 dBA threshold, about two-thirds of the share in Central Security-Widefield.

Central Security-Widefield sounds about 27% louder than Northern Security-Widefield to the human ear, a 3.5 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.

Loudest Road Corridors

The model evaluates every road in Security-Widefield using federal traffic counts, posted speeds, heavy-truck ratios, and pavement type. The source level shown is the modeled noise at the road centerline, where it is loudest. Noise drops with distance, faster in vegetated areas and slower over open pavement.

Rail Noise

Active freight rail runs through parts of Security-Widefield. 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

City Of Colorado Springs Municipal (COS) sits north of Security-Widefield. 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 60 dBA on the map's Overall layer. Blocks on the opposite side of Security-Widefield, 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 Security-Widefield

The bar chart below shows the share of Security-Widefield residents in each noise band. About 69% of residents live below the EPA's 55 dBA threshold, and roughly 4% live in blocks above 60 dBA. Long-term exposure in that range is linked to elevated stress hormones and cardiovascular risk.

How Security-Widefield Compares

Security-Widefield sits at the louder end of the spectrum. Below: how Security-Widefield's average outdoor noise and share of residents above the EPA threshold compare with Fountain, Cimarron Hills, Peyton, and Pueblo West.

Average noise level (dBA)

Security-Widefield's 54.1 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 Security-Widefield because most of either area is rural land away from major roads.

Share of residents above 55 dBA

About 37.8% of Security-Widefield 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, 42.8% of Security-Widefield'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 Security-Widefield

• 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-25 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 Security-Widefield is under tree cover (lighter than most cities), 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. City Of Colorado Springs Municipal's approach paths concentrate aviation noise to the north. Neighborhoods to the south of downtown show no measurable contribution from the airport.
