This map shows modeled outdoor noise across Magic City 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 0 Magic City residents, or 0.2%, live above that level. By land area, 0.2% of Magic City is above 55 dBA.

See how noise in Magic City compares to similar-sized cities.

Eastern Magic City sounds about 0% louder than Western Magic City 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.

How far back from Deer Creek do you need to be?

Deer Creek produces an estimated 53 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 Magic City 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 Magic City

The bar chart below shows the share of Magic City residents in each noise band. About 100% 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 Magic City Compares

Magic City sits at the quieter end of the spectrum. Below: how Magic City's average outdoor noise and share of residents above the EPA threshold compare with Gannett, Soldier, Fairfield, and Triumph.

Average noise level (dBA)

Magic City's 38.3 dBA pop-weighted average is at the quieter end of the spectrum. Idaho as a whole averages 50.6 dBA and the U.S. averages 52.0 dBA. Both are lower than Magic City because most of either area is rural land away from major roads.

Share of residents above 55 dBA

About 0.2% of Magic City residents live in blocks where outdoor levels exceed the EPA's 55 dBA threshold. That's fewer than any of its peer group. Measured by land area instead, 0.2% of Magic City's footprint sits above 55 dBA, against a Idaho average of 17.7% and a national average of 28.1%.

What This Means if You're Moving to Magic City

  • 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 Deer Creek 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 Magic City is under tree cover (about average for cities), and the dominant land cover is evergreen forest. 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.

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.
