This map shows modeled outdoor noise across Waltman 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 0 Waltman residents, or 0.0%, live above that level. By land area, 0.1% of Waltman is above 55 dBA.

Noise by Part of Waltman
Average noise levels for Waltman residents, grouped by direction from the center of Waltman. Southern Waltman carries the highest population-weighted average; Western Waltman carries the lowest. Just 0% of residents in Western Waltman live in blocks above the EPA's 55 dBA threshold, a fraction of the share in Southern Waltman.

Whisper
Southern Waltman sounds about 100% louder than Western Waltman to the human ear, a 10.0 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 Unknown do you need to be?
Unknown 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 Waltman sits under tree canopy (lighter than most cities) and roughly 0% 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 Waltman. 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.
How Noise Is Distributed Across Waltman
The bar chart below shows the share of Waltman residents in each noise band. About 100% of residents live below the EPA's 55 dBA threshold, and roughly 0% live in blocks above 60 dBA. Long-term exposure in that range is linked to elevated stress hormones and cardiovascular risk.
How Waltman Compares
Waltman sits at the quieter end of the spectrum. Below: how Waltman's average outdoor noise and share of residents above the EPA threshold compare with Red Buttes Village, Hiland, Paradise Valley, and Linch.
Average noise level (dBA)
Waltman's 30.1 dBA pop-weighted average is at the quieter end of the spectrum. Wyoming as a whole averages 48.0 dBA and the U.S. averages 52.0 dBA. Both are lower than Waltman because most of either area is rural land away from major roads.
Share of residents above 55 dBA
About 0.0% of Waltman residents live in blocks where outdoor levels exceed the EPA's 55 dBA threshold. That's fewer than any of its peer group. Measured by land area instead, 0.1% of Waltman's footprint sits above 55 dBA, against a Wyoming average of 13.3% and a national average of 28.1%.
What This Means if You're Moving to Waltman
- 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 Unknown 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 Waltman is under tree cover (lighter than most cities), and the dominant land cover is shrub / scrub. 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.
