This map shows modeled outdoor noise across Cromberg 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 5 Cromberg residents, or 2.8%, live above that level. By land area, 4.8% of Cromberg is above 55 dBA.

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

Soft rainfall
Southern Cromberg sounds about 303% louder than Eastern Cromberg to the human ear, a 20.1 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 98 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 busy restaurant.

Calculated from the model's calibrated attenuation formula. About 41% of Cromberg sits under tree canopy (heavier than most cities) and roughly 0% 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 Cromberg. 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 Cromberg
The bar chart below shows the share of Cromberg residents in each noise band. About 94% of residents live below the EPA's 55 dBA threshold, and roughly 6% live in blocks above 60 dBA. Long-term exposure in that range is linked to elevated stress hormones and cardiovascular risk.
How Cromberg Compares
Cromberg sits at the louder end of the spectrum. Below: how Cromberg's average outdoor noise and share of residents above the EPA threshold compare with Greenhorn, Sierra City, Taylorsville, and Strawberry Valley.
Average noise level (dBA)
Cromberg's 43.3 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 Cromberg because most of either area is rural land away from major roads.
Share of residents above 55 dBA
About 2.8% of Cromberg 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, 4.8% of Cromberg'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 Cromberg
- 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 41% of Cromberg is under tree cover (heavier than most cities), and the dominant land cover is evergreen forest. 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.
