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 3,579 24179 residents, or 20.5%, live above that level. By land area, 32.6% of 24179 is above 55 dBA.

Noise by Part of 24179
Average noise levels for 24179 residents, grouped by direction from the center of 24179. The highest population-weighted average is in southwestern 24179; the lowest is in northeastern 24179, where just 3% of residents live in blocks above the EPA's 55 dBA threshold, a fifth of the share in the loudest section.

Quiet suburban street at night
To the human ear, noise in southwestern 24179 sounds about 641% louder than in northeastern 24179, a 28.9 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 110 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 city bus interior.

Calculated from the model's calibrated attenuation formula. About 39% of 24179 sits under tree canopy (heavier than most zip codes) and roughly 16% 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 24179. 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 24179
The bar chart below shows the share of 24179 residents in each noise band. About 71% of residents live below the EPA's 55 dBA threshold, and roughly 8% live in blocks above 60 dBA. Long-term exposure in that range is linked to elevated stress hormones and cardiovascular risk.
How 24179 Compares
24179 sits at the quieter end of the spectrum. Below: how 24179's average outdoor noise and share of residents above the EPA threshold compare with 24014, 24017, 24015, and 24012.
Average noise level (dBA)
24179's 52.7 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 24179 because most of either area is rural land away from major roads.
Share of residents above 55 dBA
About 20.5% of 24179 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, 32.6% of 24179'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 24179
- 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 39% of 24179 is under tree cover (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.
