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 3 Soda Bay residents, or 1.6%, live above that level. By land area, 0.6% of Soda Bay is above 55 dBA.
Average noise levels for Soda Bay residents, grouped by direction from the center of Soda Bay. Southern Soda Bay carries the highest population-weighted average; Northern Soda Bay carries the lowest. Just 1% of residents in Northern Soda Bay live in blocks above the EPA's 55 dBA threshold, about half the share in Southern Soda Bay.

QuietLoud
Southern Soda Bay sounds about 56% louder than Northern Soda Bay to the human ear, a 6.4 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 66 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 33% of Soda Bay sits under tree canopy (about average for 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.

How Noise Is Distributed Across Soda Bay
The bar chart below shows the share of Soda Bay 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 Soda Bay Compares
Soda Bay sits at the quieter end of the spectrum. Below: how Soda Bay's average outdoor noise and share of residents above the EPA threshold compare with Clearlake Park, Loch Lomond, Seigler Springs, and Glenhaven.
Average noise level (dBA)
Soda Bay's 42.6 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 Soda Bay because most of either area is rural land away from major roads.
Share of residents above 55 dBA
About 1.6% of Soda Bay 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, 0.6% of Soda Bay'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 Soda Bay
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 33% of Soda Bay is under tree cover (about average for 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.
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.
