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 1,131 Braun's Farm residents, or 28.8%, live above that level. By land area, 35.7% of Braun's Farm is above 55 dBA.

See how noise in Braun's Farm compares to similar-sized neighborhoods.

Western Braun's Farm sounds about 0% louder than Eastern Braun's Farm to the human ear, a 0.0 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 State Loop 1604 do you need to be?

State Loop 1604 produces an estimated 75 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 30% of Braun's Farm sits under tree canopy (heavier than most 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 east of Braun's Farm. 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 Braun's Farm, particularly to the west, show no measurable aviation contribution. Use the Aviation toggle on the map above to isolate the airport's footprint.

How Noise Is Distributed Across Braun's Farm

The bar chart below shows the share of Braun's Farm residents in each noise band. About 73% 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 Braun's Farm Compares

Braun's Farm sits the highest among the peer group. Below: how Braun's Farm's average outdoor noise and share of residents above the EPA threshold compare with Wildhorse, Parkwood Maintenance, Braun Station West, and Culebra Park.

Average noise level (dBA)

Braun's Farm's 53.0 dBA pop-weighted average is the highest among the peer group. Texas as a whole averages 50.8 dBA and the U.S. averages 52.0 dBA. Both are lower than Braun's Farm because most of either area is rural land away from major roads.

Share of residents above 55 dBA

About 28.8% of Braun's Farm residents live in blocks where outdoor levels exceed the EPA's 55 dBA threshold. That's more than any of its peer group. Measured by land area instead, 35.7% of Braun's Farm'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 Braun's Farm

  • 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 State Loop 1604 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 30% of Braun's Farm is under tree cover (heavier than most 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 east. Neighborhoods to the west 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.

Federal datasets used:

FHWA Highway Performance Monitoring System: road geometry, traffic counts, lane configuration
U.S. DoT Bureau of Transportation Statistics National Transportation Noise Map: aviation and rail noise, road calibration ground truth
USGS / MRLC National Land Cover Database: land cover and impervious surface coverage
USDA Forest Service Tree Canopy Cover: vegetation density for sound propagation
U.S. Census Bureau TIGER/Line: block-level geography and population
U.S. EPA Levels Document: 55 dBA outdoor reference level

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.
