Western Woodlands Village sounds about 139% louder than Northern Woodlands Village to the human ear, a 12.6 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 75 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 21% of Woodlands Village sits under tree canopy (heavier than most neighborhoods) and roughly 46% 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 Woodlands Village
The bar chart below shows the share of Woodlands Village residents in each noise band. About 40% of residents live below the EPA's 55 dBA threshold, and roughly 11% live in blocks above 60 dBA. Long-term exposure in that range is linked to elevated stress hormones and cardiovascular risk.
How Woodlands Village Compares
Woodlands Village sits at the quieter end of the spectrum. Below: how Woodlands Village's average outdoor noise and share of residents above the EPA threshold compare with Sunnyside-Flagstaff, South Flagstaff, university-heights-flagstaff-az, and pine-knoll-flagstaff-az.
Average noise level (dBA)
Woodlands Village's 57.3 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 Woodlands Village because most of either area is rural land away from major roads.
Share of residents above 55 dBA
About 46.2% of Woodlands Village 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, 47.4% of Woodlands Village'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 Woodlands Village
- 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 21% of Woodlands Village is under tree cover (heavier 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.
