This map shows modeled outdoor noise across Kettleman City 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 568 Kettleman City residents, or 54.0%, live above that level. By land area, 14.8% of Kettleman City is above 55 dBA.

Noise by Part of Kettleman City
Average noise levels for Kettleman City residents, grouped by direction from the center of Kettleman City. Eastern Kettleman City carries the highest population-weighted average; Southern Kettleman City carries the lowest. Just 6% of residents in Southern Kettleman City live in blocks above the EPA's 55 dBA threshold, a fifth of the share in Eastern Kettleman City.
Central Kettleman City
58% of people above 55 dBA
Eastern Kettleman City
74% of people above 55 dBA
Northern Kettleman City
1% of people above 55 dBA
Southern Kettleman City

Western Kettleman City
2% of people above 55 dBA
Eastern Kettleman City sounds about 256% louder than Southern Kettleman City to the human ear, a 18.3 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 W Side Fwy do you need to be?
W Side Fwy 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 0% of Kettleman City sits under tree canopy (much lighter than most cities) and roughly 34% 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.
