This map shows modeled outdoor noise across 92392 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 15,162 92392 residents, or 26.6%, live above that level. By land area, 24.1% of 92392 is above 55 dBA.

Noise by Part of 92392
Average noise levels for 92392 residents, grouped by direction from the center of 92392. Central 92392 carries the highest population-weighted average; Southern 92392 carries the lowest. Just 25% of residents in Southern 92392 live in blocks above the EPA's 55 dBA threshold, three-quarters of the share in Central 92392.
Central 92392
34% of people above 55 dBA
Eastern 92392
24% of people above 55 dBA
Northern 92392
27% of people above 55 dBA
Southern 92392
25% of people above 55 dBA
Western 92392
30% of people above 55 dBA
Central 92392 sounds about 13% louder than Southern 92392 to the human ear, a 1.7 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 Mojave Fwy do you need to be?
Mojave Fwy produces an estimated 78 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.
Calculated from the model's calibrated attenuation formula. About 0% of 92392 sits under tree canopy (much lighter than most zip codes) and roughly 41% 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.
