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 3,291 SouthWest Anaheim residents, or 48.0%, live above that level. By land area, 58.9% of SouthWest Anaheim is above 55 dBA.

Noise by Part of SouthWest Anaheim
Average noise levels for SouthWest Anaheim residents, grouped by direction from the center of SouthWest Anaheim. The highest population-weighted average is in northeastern SouthWest Anaheim; the lowest is in southeastern SouthWest Anaheim, where just 40% of residents live in blocks above the EPA's 55 dBA threshold, about two-thirds of the share in the loudest section.

Normal conversation an arm’s length away
To the human ear, noise in northeastern SouthWest Anaheim sounds about 67% louder than in southeastern SouthWest Anaheim, a 7.4 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 Santa Ana Fwy do you need to be?
Santa Ana Fwy produces an estimated 80 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 4% of SouthWest Anaheim sits under tree canopy (much lighter than most neighborhoods) and roughly 67% 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
John Wayne/Orange County (SNA) sits southeast of SouthWest Anaheim. 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 SouthWest Anaheim, particularly to the northwest, show no measurable aviation contribution. Use the Aviation toggle on the map above to isolate the airport's footprint.
How Noise Is Distributed Across SouthWest Anaheim
The bar chart below shows the share of SouthWest Anaheim residents in each noise band. About 36% of residents live below the EPA's 55 dBA threshold, and roughly 36% live in blocks above 60 dBA. Long-term exposure in that range is linked to elevated stress hormones and cardiovascular risk.
How SouthWest Anaheim Compares
SouthWest Anaheim sits at the louder end of the spectrum. Below: how SouthWest Anaheim's average outdoor noise and share of residents above the EPA threshold compare with Townsend-Raitt, Henninger Park, Flower Park, and Lyon Street.
Average noise level (dBA)
SouthWest Anaheim's 57.7 dBA pop-weighted average is at the louder end of the spectrum. California as a whole averages 54.0 dBA and the U.S. averages 52.0 dBA. Both are lower than SouthWest Anaheim because most of either area is rural land away from major roads.
Share of residents above 55 dBA
About 48.0% of SouthWest Anaheim residents live in blocks where outdoor levels exceed the EPA's 55 dBA threshold. That's in the middle of its peer group. Measured by land area instead, 58.9% of SouthWest Anaheim's footprint sits above 55 dBA, against a California average of 36.0% and a national average of 28.1%.
What This Means if You're Moving to SouthWest Anaheim
- 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 Santa Ana Fwy 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 SouthWest Anaheim 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. John Wayne/Orange County's approach paths concentrate aviation noise to the southeast. Neighborhoods to the northwest of downtown show no measurable contribution from the airport.
