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 1,705 Salisbury Street residents, or 31.2%, live above that level. By land area, 38.8% of Salisbury Street is above 55 dBA.
Average noise levels for Salisbury Street residents, grouped by direction from the center of Salisbury Street. Southern Salisbury Street carries the highest population-weighted average; Northern Salisbury Street carries the lowest. Just 22% of residents in Northern Salisbury Street live in blocks above the EPA's 55 dBA threshold, about two-thirds of the share in Southern Salisbury Street.

QuietLoud
Southern Salisbury Street sounds about 14% louder than Northern Salisbury Street to the human ear, a 1.9 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 68 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 50% of Salisbury Street sits under tree canopy (much heavier than most neighborhoods) and roughly 25% 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.

How Noise Is Distributed Across Salisbury Street
The bar chart below shows the share of Salisbury Street residents in each noise band. About 61% of residents live below the EPA's 55 dBA threshold, and roughly 4% live in blocks above 60 dBA. Long-term exposure in that range is linked to elevated stress hormones and cardiovascular risk.
How Salisbury Street Compares
Salisbury Street sits the lowest among the peer group. Below: how Salisbury Street's average outdoor noise and share of residents above the EPA threshold compare with Hamilton, Indian Lake East, Hadwen Park, and North Lincoln Street.
Average noise level (dBA)
Salisbury Street's 53.9 dBA pop-weighted average is the lowest among the peer group. Massachusetts as a whole averages 54.3 dBA and the U.S. averages 52.0 dBA. Both are lower than Salisbury Street because most of either area is rural land away from major roads.
Share of residents above 55 dBA
About 31.2% of Salisbury Street 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, 38.8% of Salisbury Street's footprint sits above 55 dBA, against a Massachusetts average of 40.0% and a national average of 28.1%.
What This Means if You're Moving to Salisbury Street
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 50% of Salisbury Street is under tree cover (much heavier than most neighborhoods), 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.
