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 1,722 97496 residents, or 23.7%, live above that level. By land area, 18.9% of 97496 is above 55 dBA.

Noise by Part of 97496
Average noise levels for 97496 residents, grouped by direction from the center of 97496. The highest population-weighted average is in northern 97496; the lowest is in southwestern 97496, where just 4% of residents live in blocks above the EPA's 55 dBA threshold, a fifth of the share in the loudest section.

To the human ear, noise in northern 97496 sounds about 39% louder than in southwestern 97496, a 4.7 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 Oregon Route 42 do you need to be?
Oregon Route 42 produces an estimated 65 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 12% of 97496 sits under tree canopy (lighter than most zip codes) and roughly 30% 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 97496. 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 97496
The bar chart below shows the share of 97496 residents in each noise band. About 74% of residents live below the EPA's 55 dBA threshold, and roughly 1% live in blocks above 60 dBA. Long-term exposure in that range is linked to elevated stress hormones and cardiovascular risk.
How 97496 Compares
97496 sits at the quieter end of the spectrum. Below: how 97496's average outdoor noise and share of residents above the EPA threshold compare with 97457, 97479, 97470, and 97423.
Average noise level (dBA)
97496's 51.0 dBA pop-weighted average is at the quieter end of the spectrum. Oregon as a whole averages 52.9 dBA and the U.S. averages 52.0 dBA. Both are lower than 97496 because most of either area is rural land away from major roads.
Share of residents above 55 dBA
About 23.7% of 97496 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, 18.9% of 97496's footprint sits above 55 dBA, against a Oregon average of 24.2% and a national average of 28.1%.
What This Means if You're Moving to 97496
- 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 Oregon Route 42 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 12% of 97496 is under tree cover (lighter than most zip codes), and the dominant land cover is low-intensity developed land. 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.
