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 5,542 Hollins residents, or 34.9%, live above that level. By land area, 44.7% of Hollins is above 55 dBA.
Average noise levels for Hollins residents, grouped by direction from the center of Hollins. Western Hollins carries the highest population-weighted average; Northern Hollins carries the lowest. Just 30% of residents in Northern Hollins live in blocks above the EPA's 55 dBA threshold, three-quarters of the share in Western Hollins.

QuietLoud
Western Hollins sounds about 16% louder than Northern Hollins to the human ear, a 2.2 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 US Hwy 220 do you need to be?
US Hwy 220 produces an estimated 77 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 quiet suburban street at night.

Soft rainfall
Calculated from the model's calibrated attenuation formula. About 26% of Hollins sits under tree canopy (about average for cities) and roughly 24% 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 Hollins. 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 Hollins
The bar chart below shows the share of Hollins residents in each noise band. About 41% of residents live below the EPA's 55 dBA threshold, and roughly 9% live in blocks above 60 dBA. Long-term exposure in that range is linked to elevated stress hormones and cardiovascular risk.
How Hollins Compares
Hollins sits the highest among the peer group. Below: how Hollins's average outdoor noise and share of residents above the EPA threshold compare with Vinton, Cave Spring, Bedford, and Rocky Mount.
Average noise level (dBA)
Hollins's 55.1 dBA pop-weighted average is the highest among the peer group. Virginia as a whole averages 52.8 dBA and the U.S. averages 52.0 dBA. Both are lower than Hollins because most of either area is rural land away from major roads.
Share of residents above 55 dBA
About 34.9% of Hollins residents live in blocks where outdoor levels exceed the EPA's 55 dBA threshold. That's more than any of its peer group. Measured by land area instead, 44.7% of Hollins'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 Hollins
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 US Hwy 220 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 26% of Hollins is under tree cover (about average for cities), 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.
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.
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.
