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 1,012 Manville residents, or 35.5%, live above that level. By land area, 44.7% of Manville is above 55 dBA.

Noise by Part of Manville

Average noise levels for Manville residents, grouped by direction from the center of Manville. Western Manville carries the highest population-weighted average; Eastern Manville carries the lowest. Just 27% of residents in Eastern Manville live in blocks above the EPA's 55 dBA threshold, three-quarters of the share in Western Manville.

QuietLoud

Western Manville sounds about 61% louder than Eastern Manville to the human ear, a 6.9 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 New River Rd do you need to be?

New River Rd produces an estimated 59 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 35% of Manville sits under tree canopy (about average for cities) and roughly 44% 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 Manville. 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 Manville

The bar chart below shows the share of Manville residents in each noise band. About 67% of residents live below the EPA's 55 dBA threshold, and roughly 2% live in blocks above 60 dBA. Long-term exposure in that range is linked to elevated stress hormones and cardiovascular risk.

How Manville Compares

Manville sits the highest among the peer group. Below: how Manville's average outdoor noise and share of residents above the EPA threshold compare with Cumberland Hill, Hope, Greene, and Foster.

Average noise level (dBA)

Manville's 53.3 dBA pop-weighted average is the highest among the peer group. Rhode Island as a whole averages 53.0 dBA and the U.S. averages 52.0 dBA. Both are lower than Manville because most of either area is rural land away from major roads.

Share of residents above 55 dBA

About 35.5% of Manville 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 Manville's footprint sits above 55 dBA, against a Rhode Island average of 36.6% and a national average of 28.1%.

What This Means if You're Moving to Manville

  • 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 New River Rd 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 35% of Manville is under tree cover (about average for cities), 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.

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.

Federal datasets used:

FHWA Highway Performance Monitoring System: road geometry, traffic counts, lane configuration
U.S. DoT Bureau of Transportation Statistics National Transportation Noise Map: aviation and rail noise, road calibration ground truth
USGS / MRLC National Land Cover Database: land cover and impervious surface coverage
USDA Forest Service Tree Canopy Cover: vegetation density for sound propagation
U.S. Census Bureau TIGER/Line: block-level geography and population
U.S. EPA Levels Document: 55 dBA outdoor reference level

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.
