This map shows modeled outdoor noise across Earp 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 Earp residents, or 2.1%, live above that level. By land area, 1.8% of Earp is above 55 dBA.

Noise by Part of Earp
Average noise levels for Earp residents, grouped by direction from the center of Earp. Western Earp carries the highest population-weighted average; Southern Earp carries the lowest. Just 0% of residents in Southern Earp live in blocks above the EPA's 55 dBA threshold, a fifth of the share in Western Earp.

Quiet suburban street at night
Western Earp sounds about 317% louder than Southern Earp to the human ear, a 20.6 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 81 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 office.

Soft rainfall
Calculated from the model's calibrated attenuation formula. About 0% of Earp sits under tree canopy (much lighter than most cities) and roughly 15% 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.

Rail Noise
Active freight rail runs through parts of Earp. For most blocks the rail-only contribution is small. Combined road-plus-rail noise rarely exceeds road noise on its own. The exceptions are the handful of blocks within roughly a quarter mile of the right-of-way during pass-through hours.
Use the Rail toggle on the map above to isolate rail's contribution from road and aviation.
How Noise Is Distributed Across Earp
The bar chart below shows the share of Earp residents in each noise band. About 100% of residents live below the EPA's 55 dBA threshold, and roughly 0% live in blocks above 60 dBA. Long-term exposure in that range is linked to elevated stress hormones and cardiovascular risk.
How Earp Compares
Earp sits at the quieter end of the spectrum. Below: how Earp's average outdoor noise and share of residents above the EPA threshold compare with Parker Dam, Desert Center, Chambless, and Essex.
Average noise level (dBA)
Earp's 38.9 dBA pop-weighted average is at the quieter end of the spectrum. California as a whole averages 54.0 dBA and the U.S. averages 52.0 dBA. Both are lower than Earp because most of either area is rural land away from major roads.
Share of residents above 55 dBA
About 2.1% of Earp 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, 1.8% of Earp'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 Earp
- 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 0% of Earp is under tree cover (much lighter than most cities), and the dominant land cover is shrub / scrub. 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.
