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 4,531 Juanita residents, or 33.9%, live above that level. By land area, 35.1% of Juanita is above 55 dBA.
Average noise levels for Juanita residents, grouped by direction from the center of Juanita. Northern Juanita carries the highest population-weighted average; Western Juanita carries the lowest. Just 14% of residents in Western Juanita live in blocks above the EPA's 55 dBA threshold, a third of the share in Northern Juanita.

QuietLoud
Northern Juanita sounds about 57% louder than Western Juanita to the human ear, a 6.5 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 100TH Ave NE do you need to be?
100TH Ave NE produces an estimated 66 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 38% of Juanita sits under tree canopy (much heavier than most neighborhoods) and roughly 45% 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 Juanita. 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 Juanita, 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 Juanita
The bar chart below shows the share of Juanita residents in each noise band. About 70% of residents live below the EPA's 55 dBA threshold, and roughly 6% live in blocks above 60 dBA. Long-term exposure in that range is linked to elevated stress hormones and cardiovascular risk.
How Juanita Compares
Juanita sits at the quieter end of the spectrum. Below: how Juanita's average outdoor noise and share of residents above the EPA threshold compare with Education Hill, Bridle Trails, Wallingford, and Lake Hills.
Average noise level (dBA)
Juanita's 53.0 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 Juanita because most of either area is rural land away from major roads.
Share of residents above 55 dBA
About 33.9% of Juanita 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, 35.1% of Juanita'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 Juanita
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 100TH 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 Juanita 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.
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.
