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 1,923 Scurry County residents, or 20.0%, live above that level. By land area, 14.1% of Scurry County is above 55 dBA.
85.9% below 55 dBA

Noise by Part of Scurry County
Average noise levels for Scurry County residents, grouped by direction from the center of Scurry County. The highest population-weighted average is in northeastern Scurry County; the lowest is in southern Scurry County, where just 2% of residents live in blocks above the EPA's 55 dBA threshold, a fifth of the share in the loudest section.

To the human ear, noise in northeastern Scurry County sounds about 95% louder than in southern Scurry County, a 9.6 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 I-20 do you need to be?
I-20 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 0% of Scurry County sits under tree canopy (much lighter than most counties) and roughly 25% 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 Scurry County. 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 Scurry County
The bar chart below shows the share of Scurry County residents in each noise band. About 79% of residents live below the EPA's 55 dBA threshold, and roughly 2% live in blocks above 60 dBA. Long-term exposure in that range is linked to elevated stress hormones and cardiovascular risk.
How Scurry County Compares
Scurry County sits at the quieter end of the spectrum. Below: how Scurry County's average outdoor noise and share of residents above the EPA threshold compare with Mitchell County, Nolan County, Jones County, and Howard County.
Average noise level (dBA)
Scurry County's 46.2 dBA pop-weighted average is at the quieter end of the spectrum. Texas as a whole averages 50.8 dBA and the U.S. averages 52.0 dBA. Both are lower than Scurry County because most of either area is rural land away from major roads.
Share of residents above 55 dBA
About 20.0% of Scurry County 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, 14.1% of Scurry County's footprint sits above 55 dBA, against a Texas average of 22.8% and a national average of 28.1%.
What This Means if You're Moving to Scurry County
- 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-20 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 Scurry County is under tree cover (much lighter than most counties), 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.
