This map shows modeled outdoor noise across Alvadore 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 95 Alvadore residents, or 56.7%, live above that level. By land area, 62.9% of Alvadore is above 55 dBA.
Average noise levels for Alvadore residents, grouped by direction from the center of Alvadore. Eastern Alvadore carries the highest population-weighted average; Western Alvadore carries the lowest. Just 3% of residents in Western Alvadore live in blocks above the EPA's 55 dBA threshold, a fifth of the share in Eastern Alvadore.

Eastern Alvadore sounds about 289% louder than Western Alvadore to the human ear, a 19.6 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 105 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 city bus interior.

Calculated from the model's calibrated attenuation formula. About 0% of Alvadore sits under tree canopy (much lighter than most cities) and roughly 3% 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.

Airport Noise
Mahlon Sweet Field (EUG) sits southeast of Alvadore. The U.S. Department of Transportation models aviation noise around this airport from federal traffic data, and the model uses those federal measurements rather than synthetic predictions.
Blocks under the approach and departure paths carry combined road-plus-aviation noise, with some exceeding 105 dBA on the map's Overall layer. Blocks on the opposite side of Alvadore, particularly to the northwest, show no measurable aviation contribution. Use the Aviation toggle on the map above to isolate the airport's footprint.
How Noise Is Distributed Across Alvadore
The bar chart below shows the share of Alvadore residents in each noise band. About 43% of residents live below the EPA's 55 dBA threshold, and roughly 48% live in blocks above 60 dBA. Long-term exposure in that range is linked to elevated stress hormones and cardiovascular risk.
How Alvadore Compares
Alvadore sits the highest among the peer group. Below: how Alvadore's average outdoor noise and share of residents above the EPA threshold compare with Glenbrook, Greenleaf, Bellfountain, and Tide.
Average noise level (dBA)
Alvadore's 55.8 dBA pop-weighted average is the highest among the peer group. Oregon as a whole averages 52.9 dBA and the U.S. averages 52.0 dBA. Both are lower than Alvadore because most of either area is rural land away from major roads.
Share of residents above 55 dBA
About 56.7% of Alvadore residents live in blocks where outdoor levels exceed the EPA's 55 dBA threshold. That's more than any of its peer group. Measured by land area instead, 62.9% of Alvadore'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 Alvadore
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 Alvadore is under tree cover (much lighter than most cities), and the dominant land cover is pasture / hay. 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.
Airport noise is directional. Mahlon Sweet Field's approach paths concentrate aviation noise to the southeast. Neighborhoods to the northwest of downtown show no measurable contribution from the airport.
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.
