This map shows modeled outdoor noise across North Loop at 100-meter resolution, combining road, aviation, and rail sources. Green areas measure below 45 dBA. Orange and red exceed the EPA's 55 dBA outdoor threshold linked to long-term health effects. Use the layer toggles to view each source on its own or all together.

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 1,502 North Loop residents, or 64.9%, live above that level. By land area, 54.4% of North Loop is above 55 dBA.

Noise by Part of North Loop
Average noise levels for North Loop residents, grouped by direction from the center of North Loop. The highest population-weighted average is in eastern North Loop; the lowest is in western North Loop, where just 15% of residents live in blocks above the EPA's 55 dBA threshold, a third of the share in the loudest section.

Quiet office to normal conversation
To the human ear, noise in eastern North Loop sounds about 300% louder than in western North Loop, a 20.0 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 US Hwy 290 do you need to be?
US Hwy 290 produces an estimated 79 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 11% of North Loop sits under tree canopy (lighter than most neighborhoods) and roughly 47% 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 North Loop. 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 North Loop, 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 North Loop
The bar chart below shows the share of North Loop residents in each noise band. About 36% of residents live below the EPA's 55 dBA threshold, and roughly 16% live in blocks above 60 dBA. Long-term exposure in that range is linked to elevated stress hormones and cardiovascular risk.
How North Loop Compares
North Loop sits the highest among the peer group. Below: how North Loop's average outdoor noise and share of residents above the EPA threshold compare with Rosewood, Saint Johns, North University, and Holly.
Average noise level (dBA)
North Loop's 57.2 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 North Loop because most of either area is rural land away from major roads.
Share of residents above 55 dBA
About 64.9% of North Loop 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, 54.4% of North Loop'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 North Loop
- 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 290 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 11% of North Loop 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. 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.
