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 16,636 23112 residents, or 32.8%, live above that level. By land area, 38.4% of 23112 is above 55 dBA.

Noise by Part of 23112
Average noise levels for 23112 residents, grouped by direction from the center of 23112. The highest population-weighted average is in eastern 23112; the lowest is in northwestern 23112, where just 17% of residents live in blocks above the EPA's 55 dBA threshold, about half the share in the loudest section.

Quiet office to normal conversation
To the human ear, noise in eastern 23112 sounds about 64% louder than in northwestern 23112, a 7.1 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 State Hwy 288 do you need to be?
State Hwy 288 produces an estimated 73 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.

Soft rainfall
Calculated from the model's calibrated attenuation formula. About 54% of 23112 sits under tree canopy (much heavier than most zip codes) and roughly 20% 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.

Rail Noise
Active freight rail runs through parts of 23112. 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.
Use the Rail toggle on the map above to isolate rail's contribution from road and aviation.
How Noise Is Distributed Across 23112
The bar chart below shows the share of 23112 residents in each noise band. About 43% of residents live below the EPA's 55 dBA threshold, and roughly 7% live in blocks above 60 dBA. Long-term exposure in that range is linked to elevated stress hormones and cardiovascular risk.
How 23112 Compares
23112 sits at the quieter end of the spectrum. Below: how 23112's average outdoor noise and share of residents above the EPA threshold compare with 23832, 23234, 23225, and 23223.
Average noise level (dBA)
23112's 55.1 dBA pop-weighted average is at the quieter end of the spectrum. Virginia as a whole averages 52.8 dBA and the U.S. averages 52.0 dBA. Both are lower than 23112 because most of either area is rural land away from major roads.
Share of residents above 55 dBA
About 32.8% of 23112 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, 38.4% of 23112's footprint sits above 55 dBA, against a Virginia average of 30.0% and a national average of 28.1%.
What This Means if You're Moving to 23112
- 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 State Hwy 288 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 54% of 23112 is under tree cover (much heavier than most zip codes), and the dominant land cover is low-density developed open space. 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.
