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 695 Hollywood Park residents, or 26.4%, live above that level. By land area, 20.7% of Hollywood Park is above 55 dBA.

Noise by Part of Hollywood Park
Average noise levels for Hollywood Park residents, grouped by direction from the center of Hollywood Park. The highest population-weighted average is in southeastern Hollywood Park; the lowest is in northwestern Hollywood Park, where just 26% of residents live in blocks above the EPA's 55 dBA threshold, roughly the same as the share in the loudest section.

Quiet office to normal conversation
To the human ear, noise in southeastern Hollywood Park sounds about 111% louder than in northwestern Hollywood Park, a 10.8 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 US Hwy 281 do you need to be?
US Hwy 281 produces an estimated 78 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 suburban street at night.

Soft rainfall
Calculated from the model's calibrated attenuation formula. About 22% of Hollywood Park sits under tree canopy (about average for cities) and roughly 26% 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 Hollywood Park. 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 Hollywood Park, 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 Hollywood Park
The bar chart below shows the share of Hollywood Park residents in each noise band. About 70% of residents live below the EPA's 55 dBA threshold, and roughly 12% live in blocks above 60 dBA. Long-term exposure in that range is linked to elevated stress hormones and cardiovascular risk.
How Hollywood Park Compares
Hollywood Park sits at the quieter end of the spectrum. Below: how Hollywood Park's average outdoor noise and share of residents above the EPA threshold compare with Terrell Hills, Castle Hills, Alamo Heights, and Balcones Heights.
Average noise level (dBA)
Hollywood Park's 53.3 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 Hollywood Park because most of either area is rural land away from major roads.
Share of residents above 55 dBA
About 26.4% of Hollywood Park 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, 20.7% of Hollywood Park'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 Hollywood Park
- 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 US Hwy 281 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 Hollywood Park is under tree cover (about average for cities), 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 south. Neighborhoods to the north of downtown show no measurable contribution from the airport.
