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 2,872 Broadmeadow Brook residents, or 32.5%, live above that level. By land area, 39.8% of Broadmeadow Brook is above 55 dBA.
Average noise levels for Broadmeadow Brook residents, grouped by direction from the center of Broadmeadow Brook. Southern Broadmeadow Brook carries the highest population-weighted average; Northern Broadmeadow Brook carries the lowest. Just 34% of residents in Northern Broadmeadow Brook live in blocks above the EPA's 55 dBA threshold, three-quarters of the share in Southern Broadmeadow Brook.

QuietLoud
Southern Broadmeadow Brook sounds about 39% louder than Northern Broadmeadow Brook to the human ear, a 4.8 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 95 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 busy restaurant.

Calculated from the model's calibrated attenuation formula. About 54% of Broadmeadow Brook sits under tree canopy (much heavier than most neighborhoods) and roughly 27% 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 Broadmeadow Brook. 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 Broadmeadow Brook
The bar chart below shows the share of Broadmeadow Brook residents in each noise band. About 75% 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 Broadmeadow Brook Compares
Broadmeadow Brook sits at the quieter end of the spectrum. Below: how Broadmeadow Brook's average outdoor noise and share of residents above the EPA threshold compare with Main Middle, Forest Grove, Tatnuck, and University Park.
Average noise level (dBA)
Broadmeadow Brook's 54.3 dBA pop-weighted average is at the quieter end of the spectrum. Massachusetts as a whole averages 54.3 dBA and the U.S. averages 52.0 dBA. Both are lower than Broadmeadow Brook because most of either area is rural land away from major roads.
Share of residents above 55 dBA
About 32.5% of Broadmeadow Brook 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, 39.8% of Broadmeadow Brook'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 Broadmeadow Brook
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 54% of Broadmeadow Brook is under tree cover (much heavier than most neighborhoods), and the dominant land cover is deciduous forest. 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.
