This map shows modeled outdoor noise across Victory Heights 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 2,480 Victory Heights residents, or 57.3%, live above that level. By land area, 59.6% of Victory Heights is above 55 dBA.

Noise by Part of Victory Heights
Average noise levels for Victory Heights residents, grouped by direction from the center of Victory Heights. The highest population-weighted average is in northeastern Victory Heights; the lowest is in northwestern Victory Heights, where just 45% of residents live in blocks above the EPA's 55 dBA threshold, roughly the same as the share in the loudest section.
Northeastern Victory Heights
52% of people above 55 dBA
Central Victory Heights
55% of people above 55 dBA
Northern Victory Heights
44% of people above 55 dBA
Southern Victory Heights
68% of people above 55 dBA
Northwestern Victory Heights
45% of people above 55 dBA
To the human ear, noise in northeastern Victory Heights sounds about 44% louder than in northwestern Victory Heights, a 5.3 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.
Airport Noise
Seattle-Tacoma International (SEA) sits south of Victory Heights. The U.S. Department of Transportation measures aviation noise around this airport directly, 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 75 dBA on the map's Overall layer. Blocks on the opposite side of Victory Heights, particularly to the north, show no measurable aviation contribution. Use the Aviation toggle on the map above to isolate the airport's footprint.
How Noise Is Distributed Across Victory Heights
The bar chart below shows the share of Victory Heights residents in each noise band. About 56% of residents live below the EPA's 55 dBA threshold, and roughly 9% live in blocks above 60 dBA. Long-term exposure in that range is linked to elevated stress hormones and cardiovascular risk.
How Victory Heights Compares
Victory Heights sits at the quieter end of the spectrum. Below: how Victory Heights's average outdoor noise and share of residents above the EPA threshold compare with Northgate, Crown Hill, View Ridge, and Laurelhurst.
Average noise level (dBA)
Victory Heights's 55.1 dBA pop-weighted average is at the quieter end of the spectrum. Washington as a whole averages 51.3 dBA and the U.S. averages 52.0 dBA. Both are lower than Victory Heights because most of either area is rural land away from major roads.
Share of residents above 55 dBA
About 57.3% of Victory Heights 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, 59.6% of Victory Heights's footprint sits above 55 dBA, against a Washington average of 27.7% and a national average of 28.1%.
What This Means if You're Moving to Victory Heights
- 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 20TH Ave NE 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 38% of Victory Heights is under tree cover (much heavier than most neighborhoods), 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.
- Airport noise is directional. Seattle-Tacoma International's approach paths concentrate aviation noise to the south. Neighborhoods to the north 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.
Federal datasets used:
FHWA Highway Performance Monitoring System: road geometry, traffic counts, lane configuration
U.S. DoT Bureau of Transportation Statistics National Transportation Noise Map: aviation and rail noise, road calibration ground truth
USGS / MRLC National Land Cover Database: land cover and impervious surface coverage
USDA Forest Service Tree Canopy Cover: vegetation density for sound propagation
U.S. Census Bureau TIGER/Line: block-level geography and population
U.S. EPA Levels Document: 55 dBA outdoor reference level
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.
