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 4,358 Stone Oak residents, or 31.9%, live above that level. By land area, 34.7% of Stone Oak is above 55 dBA.
Average noise levels for Stone Oak residents, grouped by direction from the center of Stone Oak. Eastern Stone Oak carries the highest population-weighted average; Central Stone Oak carries the lowest. Just 23% of residents in Central Stone Oak live in blocks above the EPA's 55 dBA threshold, roughly the same as the share in Eastern Stone Oak.

QuietLoud
Eastern Stone Oak sounds about 33% louder than Central Stone Oak to the human ear, a 4.1 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 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 12% of Stone Oak sits under tree canopy (about average for neighborhoods) and roughly 48% 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
San Antonio International (SAT) sits south of Stone Oak. 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 65 dBA on the map's Overall layer. Blocks on the opposite side of Stone Oak, particularly to the north, show no measurable aviation contribution. Use the Aviation toggle on the map above to isolate the airport's footprint.
How Noise Is Distributed Across Stone Oak
The bar chart below shows the share of Stone Oak residents in each noise band. About 52% of residents live below the EPA's 55 dBA threshold, and roughly 9% live in blocks above 60 dBA. Long-term exposure in that range is linked to elevated stress hormones and cardiovascular risk.
How Stone Oak Compares
Stone Oak sits at the louder end of the spectrum. Below: how Stone Oak's average outdoor noise and share of residents above the EPA threshold compare with Vance Jackson, Great Northwest, Alamo Farmsteads-Babcock Road, and Heritage.
Average noise level (dBA)
Stone Oak's 54.4 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 Stone Oak because most of either area is rural land away from major roads.
Share of residents above 55 dBA
About 31.9% of Stone Oak 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, 34.7% of Stone Oak'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 Stone Oak
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 12% of Stone Oak is under tree cover (about average for neighborhoods), and the dominant land cover is medium-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. San Antonio International's approach paths concentrate aviation noise to the south. Neighborhoods to the north of downtown show no measurable contribution from the airport.
Sources & Methodology
The BestNeighborhood noise model is calibrated against nearly one million federal ground-truth measurements across four states. Road noise is computed from segment-level federal traffic data and propagated outward using physics-based acoustic decay, with attenuation rates that depend on the surrounding land cover.
All inputs are published federal datasets. Block-level noise is computed by combining road, rail, and aviation sound sources in the energy domain, the same physics used in professional environmental noise assessments. Read the full methodology.
