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 905 Mission San Jose residents, or 23.9%, live above that level. By land area, 27.6% of Mission San Jose is above 55 dBA.
Average noise levels for Mission San Jose residents, grouped by direction from the center of Mission San Jose. Southern Mission San Jose carries the highest population-weighted average; Central Mission San Jose carries the lowest. Just 4% of residents in Central Mission San Jose live in blocks above the EPA's 55 dBA threshold, a fifth of the share in Southern Mission San Jose.

QuietLoud
Southern Mission San Jose sounds about 41% louder than Central Mission San Jose to the human ear, a 5.0 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 do you need to be?
produces an estimated 71 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 8% of Mission San Jose sits under tree canopy (lighter than most neighborhoods) and roughly 39% 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 Mission San Jose. 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
San Antonio International (SAT) sits north of Mission San Jose. 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 Mission San Jose, 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 Mission San Jose
The bar chart below shows the share of Mission San Jose residents in each noise band. About 74% 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 Mission San Jose Compares
Mission San Jose sits the lowest among the peer group. Below: how Mission San Jose's average outdoor noise and share of residents above the EPA threshold compare with Highland Park, Quintana Community, Hot Wells, and Monte Vista.
Average noise level (dBA)
Mission San Jose's 53.0 dBA pop-weighted average is the lowest among the peer group. Texas as a whole averages 50.8 dBA and the U.S. averages 52.0 dBA. Both are lower than Mission San Jose because most of either area is rural land away from major roads.
Share of residents above 55 dBA
About 23.9% of Mission San Jose 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, 27.6% of Mission San Jose'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 Mission San Jose
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 8% of Mission San Jose is under tree cover (lighter than most neighborhoods), 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. San Antonio International's approach paths concentrate aviation noise to the north. Neighborhoods to the south 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.
