This map shows modeled outdoor noise across Eastside 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 1,162 Eastside residents, or 30.4%, live above that level. By land area, 36.1% of Eastside is above 55 dBA.

Noise by Part of Eastside
Average noise levels for Eastside residents, grouped by direction from the center of Eastside. The highest population-weighted average is in eastern Eastside; the lowest is in western Eastside, where just 20% of residents live in blocks above the EPA's 55 dBA threshold, about two-thirds of the share in the loudest section.
Eastern Eastside
32% of people above 55 dBA
Northeastern Eastside
32% of people above 55 dBA
Northwestern Eastside
28% of people above 55 dBA
Southwestern Eastside
26% of people above 55 dBA
Western Eastside
20% of people above 55 dBA
To the human ear, noise in eastern Eastside sounds about 59% louder than in western Eastside, a 6.7 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 Noise Is Distributed Across Eastside
The bar chart below shows the share of Eastside residents in each noise band. About 64% of residents live below the EPA's 55 dBA threshold, and roughly 5% live in blocks above 60 dBA. Long-term exposure in that range is linked to elevated stress hormones and cardiovascular risk.
How Eastside Compares
Eastside sits the highest among the peer group. Below: how Eastside's average outdoor noise and share of residents above the EPA threshold compare with Harrison East-South, Houghton, Civano, and El Gheko.
Average noise level (dBA)
Eastside's 54.4 dBA pop-weighted average is the highest among the peer group. Arizona as a whole averages 53.0 dBA and the U.S. averages 52.0 dBA. Both are lower than Eastside because most of either area is rural land away from major roads.
Share of residents above 55 dBA
About 30.4% of Eastside residents live in blocks where outdoor levels exceed the EPA's 55 dBA threshold. That's more than any of its peer group. Measured by land area instead, 36.1% of Eastside's footprint sits above 55 dBA, against a Arizona average of 28.3% and a national average of 28.1%.
What This Means if You're Moving to Eastside
- 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 Eastside is under tree cover (much lighter 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.
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.
