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 4,934 Georgian Acres residents, or 72.5%, live above that level. By land area, 49.7% of Georgian Acres is above 55 dBA.
Average noise levels for Georgian Acres residents, grouped by direction from the center of Georgian Acres. Southern Georgian Acres carries the highest population-weighted average; Northern Georgian Acres carries the lowest. Just 33% of residents in Northern Georgian Acres live in blocks above the EPA's 55 dBA threshold, a third of the share in Southern Georgian Acres.

QuietLoud
Southern Georgian Acres sounds about 323% louder than Northern Georgian Acres to the human ear, a 20.8 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 183 do you need to be?
US Hwy 183 produces an estimated 76 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 4% of Georgian Acres sits under tree canopy (much lighter than most neighborhoods) and roughly 58% 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
Austin-Bergstrom International (AUS) sits south of Georgian Acres. The U.S. Department of Transportation measures aviation noise around this airport directly, 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 75 dBA on the map's Overall layer. Blocks on the opposite side of Georgian Acres, 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 Georgian Acres
The bar chart below shows the share of Georgian Acres residents in each noise band. About 17% of residents live below the EPA's 55 dBA threshold, and roughly 52% live in blocks above 60 dBA. Long-term exposure in that range is linked to elevated stress hormones and cardiovascular risk.
How Georgian Acres Compares
Georgian Acres sits the highest among the peer group. Below: how Georgian Acres's average outdoor noise and share of residents above the EPA threshold compare with Heritage Hills, Windsor Hills, North Lamar, and Windsor Park.
Average noise level (dBA)
Georgian Acres's 64.2 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 Georgian Acres because most of either area is rural land away from major roads.
Share of residents above 55 dBA
About 72.5% of Georgian Acres 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, 49.7% of Georgian Acres'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 Georgian Acres
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 183 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 4% of Georgian Acres is under tree cover (much lighter 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. Austin-Bergstrom 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.
