Noise by Part of O Henry Oaks

Average noise levels for O Henry Oaks residents, grouped by direction from the center of O Henry Oaks. The highest population-weighted average is in southeastern O Henry Oaks; the lowest is in western O Henry Oaks, where just 41% of residents live in blocks above the EPA's 55 dBA threshold, three-quarters of the share in the loudest section.

To the human ear, noise in southeastern O Henry Oaks sounds about 41% louder than in western O Henry Oaks, a 5.0 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.

Rail Noise

Active freight rail runs through parts of O Henry Oaks. For most blocks the rail-only contribution is small. Combined road-plus-rail noise rarely exceeds road noise on its own. The exceptions are the handful of blocks within roughly a quarter mile of the right-of-way during pass-through hours.

What This Means if You're Moving to O Henry Oaks

• 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 Ns-918 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 32% of O Henry Oaks is under tree cover (much heavier than most neighborhoods), and the dominant land cover is low-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.
