This map shows modeled outdoor noise across Oljato-Monument Valley 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 Oljato-Monument Valley residents, or 0.8%, live above that level. By land area, 1.6% of Oljato-Monument Valley is above 55 dBA.

How Noise Is Distributed Across Oljato-Monument Valley
The bar chart below shows the share of Oljato-Monument Valley 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 Oljato-Monument Valley Compares
Oljato-Monument Valley sits at the quieter end of the spectrum. Below: how Oljato-Monument Valley's average outdoor noise and share of residents above the EPA threshold compare with Tes Nez Iah, Dennehotso, Rock Point, and Rare Metals.
Average noise level (dBA)
Oljato-Monument Valley's 32.2 dBA pop-weighted average is at the quieter end of the spectrum. Arizona as a whole averages 53.0 dBA and the U.S. averages 52.0 dBA. Both are lower than Oljato-Monument Valley because most of either area is rural land away from major roads.
Share of residents above 55 dBA
About 0.8% of Oljato-Monument Valley 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, 1.6% of Oljato-Monument Valley'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 Oljato-Monument Valley
- 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 ~~u~163~~~~~~~~~~~~~~~~~~~~~~~~~ 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 Oljato-Monument Valley is under tree cover (much lighter than most cities), and the dominant land cover is shrub / scrub. 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.
