This map shows modeled outdoor noise across West University 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 3,218 West University residents, or 78.8%, live above that level. By land area, 85.0% of West University is above 55 dBA.

Noise by Part of West University
Average noise levels for West University residents, grouped by direction from the center of West University. The highest population-weighted average is in northern West University; the lowest is in southern West University, where just 55% of residents live in blocks above the EPA's 55 dBA threshold, about two-thirds of the share in the loudest section.

To the human ear, noise in northern West University sounds about 17% louder than in southern West University, a 2.3 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 67 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 8% of West University sits under tree canopy (lighter than most neighborhoods) and roughly 70% 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 northwest of West University. 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 55 dBA on the map's Overall layer. Blocks on the opposite side of West University, particularly to the southeast, show no measurable aviation contribution. Use the Aviation toggle on the map above to isolate the airport's footprint.
How Noise Is Distributed Across West University
The bar chart below shows the share of West University residents in each noise band. About 12% of residents live below the EPA's 55 dBA threshold, and roughly 44% live in blocks above 60 dBA. Long-term exposure in that range is linked to elevated stress hormones and cardiovascular risk.
How West University Compares
West University sits the highest among the peer group. Below: how West University's average outdoor noise and share of residents above the EPA threshold compare with Fairmount, U of O Campus, Jefferson Westside, and Far West Eugene.
Average noise level (dBA)
West University's 59.5 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 West University because most of either area is rural land away from major roads.
Share of residents above 55 dBA
About 78.8% of West University 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, 85.0% of West University'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 West University
- 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 8% of West University is under tree cover (lighter than most neighborhoods), and the dominant land cover is medium-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.
- Airport noise is directional. Mahlon Sweet Field's approach paths concentrate aviation noise to the northwest. Neighborhoods to the southeast of downtown show no measurable contribution from the airport.
