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 917 Campbell Park residents, or 33.7%, live above that level. By land area, 40.6% of Campbell Park is above 55 dBA.

Noise by Part of Campbell Park

Average noise levels for Campbell Park residents, grouped by direction from the center of Campbell Park. Central Campbell Park carries the highest population-weighted average; Eastern Campbell Park carries the lowest. Just 0% of residents in Eastern Campbell Park live in blocks above the EPA's 55 dBA threshold, a fifth of the share in Central Campbell Park.

QuietLoud

Central Campbell Park sounds about 258% louder than Eastern Campbell Park to the human ear, a 18.4 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 69 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 Campbell Park sits under tree canopy (about average for neighborhoods) 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.

Airport Noise

Ted Stevens Anchorage International (ANC) sits west of Campbell Park. 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 45 dBA on the map's Overall layer. Blocks on the opposite side of Campbell Park, particularly to the east, show no measurable aviation contribution. Use the Aviation toggle on the map above to isolate the airport's footprint.

How Noise Is Distributed Across Campbell Park

The bar chart below shows the share of Campbell Park residents in each noise band. About 66% of residents live below the EPA's 55 dBA threshold, and roughly 10% live in blocks above 60 dBA. Long-term exposure in that range is linked to elevated stress hormones and cardiovascular risk.

How Campbell Park Compares

Campbell Park sits the lowest among the peer group. Below: how Campbell Park's average outdoor noise and share of residents above the EPA threshold compare with Turnagain, Scenic Foothills, Mid-Hillside, and University Area.

Average noise level (dBA)

Campbell Park's 48.9 dBA pop-weighted average is the lowest among the peer group. Alaska as a whole averages 46.7 dBA and the U.S. averages 52.0 dBA. Both are lower than Campbell Park because most of either area is rural land away from major roads.

Share of residents above 55 dBA

About 33.7% of Campbell Park 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, 40.6% of Campbell Park'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 Campbell Park

  • 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 0% of Campbell Park is under tree cover (about average for neighborhoods), 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.
  • Airport noise is directional. Ted Stevens Anchorage International's approach paths concentrate aviation noise to the west. Neighborhoods to the east 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.
