This map shows modeled outdoor noise across Ravenna 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 2,919 Ravenna residents, or 38.1%, live above that level. By land area, 38.3% of Ravenna is above 55 dBA.

Noise by Part of Ravenna
Average noise levels for Ravenna residents, grouped by direction from the center of Ravenna. The highest population-weighted average is in western Ravenna; the lowest is in eastern Ravenna, where just 24% of residents live in blocks above the EPA's 55 dBA threshold, about half the share in the loudest section.

Quiet office to normal conversation
To the human ear, noise in western Ravenna sounds about 65% louder than in eastern Ravenna, a 7.2 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 35TH Ave NE do you need to be?
35TH Ave NE produces an estimated 56 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 35% of Ravenna sits under tree canopy (much heavier than most neighborhoods) and roughly 54% 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
Seattle-Tacoma International (SEA) sits south of Ravenna. 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 45 dBA on the map's Overall layer. Blocks on the opposite side of Ravenna, 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 Ravenna
The bar chart below shows the share of Ravenna residents in each noise band. About 63% 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 Ravenna Compares
Ravenna sits the lowest among the peer group. Below: how Ravenna's average outdoor noise and share of residents above the EPA threshold compare with Green Lake, Phinney Ridge, Broadview, and Haller Lake.
Average noise level (dBA)
Ravenna's 53.0 dBA pop-weighted average is the lowest among the peer group. Washington as a whole averages 51.3 dBA and the U.S. averages 52.0 dBA. Both are lower than Ravenna because most of either area is rural land away from major roads.
Share of residents above 55 dBA
About 38.1% of Ravenna 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, 38.3% of Ravenna'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 Ravenna
- 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 35TH 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 35% of Ravenna is under tree cover (much heavier 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. 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.
