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 2,327 Kamala Park residents, or 50.8%, live above that level. By land area, 51.2% of Kamala Park is above 55 dBA.
Average noise levels for Kamala Park residents, grouped by direction from the center of Kamala Park. Southern Kamala Park carries the highest population-weighted average; Western Kamala Park carries the lowest. Just 11% of residents in Western Kamala Park live in blocks above the EPA's 55 dBA threshold, a fifth of the share in Southern Kamala Park.

QuietLoud
Southern Kamala Park sounds about 57% louder than Western Kamala Park to the human ear, a 6.5 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 do you need to be?
produces an estimated 67 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 1% of Kamala Park sits under tree canopy (much lighter than most neighborhoods) and roughly 56% 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.

How Noise Is Distributed Across Kamala Park
The bar chart below shows the share of Kamala Park residents in each noise band. About 61% of residents live below the EPA's 55 dBA threshold, and roughly 11% live in blocks above 60 dBA. Long-term exposure in that range is linked to elevated stress hormones and cardiovascular risk.
How Kamala Park Compares
Kamala Park sits at the louder end of the spectrum. Below: how Kamala Park's average outdoor noise and share of residents above the EPA threshold compare with Cal-Gisler, Lemonwood Eastmont, South Bank, and South Winds.
Average noise level (dBA)
Kamala Park's 54.9 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 Kamala Park because most of either area is rural land away from major roads.
Share of residents above 55 dBA
About 50.8% of Kamala Park 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, 51.2% of Kamala Park'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 Kamala 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 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 1% of Kamala Park 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.
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.
