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 12 Eielson Afb residents, or 2.7%, live above that level. By land area, 4.3% of Eielson Afb is above 55 dBA.
Southern Eielson Afb sounds about 0% louder than Western Eielson Afb to the human ear, a 0.0 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.

Loudest Road Corridors
The model evaluates every road in Eielson Afb using federal traffic counts, posted speeds, heavy-truck ratios, and pavement type. The source level shown is the modeled noise at the road centerline, where it is loudest. Noise drops with distance, faster in vegetated areas and slower over open pavement.

How far back from A2 do you need to be?
A2 produces an estimated 71 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 0% of Eielson Afb sits under tree canopy (about average for cities) and roughly 0% 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.
How Noise Is Distributed Across Eielson Afb
The bar chart below shows the share of Eielson Afb residents in each noise band. About 96% 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 Eielson Afb Compares
Eielson Afb sits the highest among the peer group. Below: how Eielson Afb's average outdoor noise and share of residents above the EPA threshold compare with Salcha, Pleasant Valley, Two Rivers, and Harding-Birch Lakes.
Average noise level (dBA)
Eielson Afb's 45.3 dBA pop-weighted average is the highest among the peer group. Alaska as a whole averages 46.7 dBA and the U.S. averages 52.0 dBA. Both are lower than Eielson Afb because most of either area is rural land away from major roads.
Share of residents above 55 dBA
About 2.7% of Eielson Afb 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, 4.3% of Eielson Afb's footprint sits above 55 dBA, against a Alaska average of 11.4% and a national average of 28.1%.
What This Means if You're Moving to Eielson Afb
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 A2 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 Eielson Afb is under tree cover (about average for cities), and the dominant land cover is . 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.
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.
