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 92 77872 residents, or 5.1%, live above that level. By land area, 12.0% of 77872 is above 55 dBA.

Noise by Part of 77872
Average noise levels for 77872 residents, grouped by direction from the center of 77872. The highest population-weighted average is in southwestern 77872; the lowest is in northern 77872, where just 1% of residents live in blocks above the EPA's 55 dBA threshold, three-quarters of the share in the loudest section.

Quiet suburban street at night
To the human ear, noise in southwestern 77872 sounds about 88% louder than in northern 77872, a 9.1 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 88 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 quiet office to normal conversation.

Calculated from the model's calibrated attenuation formula. About 22% of 77872 sits under tree canopy (about average for zip codes) and roughly 2% 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 77872. 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 77872
The bar chart below shows the share of 77872 residents in each noise band. About 91% of residents live below the EPA's 55 dBA threshold, and roughly 3% live in blocks above 60 dBA. Long-term exposure in that range is linked to elevated stress hormones and cardiovascular risk.
How 77872 Compares
77872 sits at the louder end of the spectrum. Below: how 77872's average outdoor noise and share of residents above the EPA threshold compare with 77871, 77861, 75852, and 77831.
Average noise level (dBA)
77872's 42.9 dBA pop-weighted average is at the louder end of the spectrum. Texas as a whole averages 50.8 dBA and the U.S. averages 52.0 dBA. Both are lower than 77872 because most of either area is rural land away from major roads.
Share of residents above 55 dBA
About 5.1% of 77872 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, 12.0% of 77872'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 77872
- 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 22% of 77872 is under tree cover (about average for zip codes), and the dominant land cover is pasture / hay. 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.
