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 1,586 East Walpole residents, or 33.9%, live above that level. By land area, 43.3% of East Walpole is above 55 dBA.
Average noise levels for East Walpole residents, grouped by direction from the center of East Walpole. Southern East Walpole carries the highest population-weighted average; Western East Walpole carries the lowest. Just 19% of residents in Western East Walpole live in blocks above the EPA's 55 dBA threshold, about half the share in Southern East Walpole.

QuietLoud
Southern East Walpole sounds about 67% louder than Western East Walpole to the human ear, a 7.4 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 I-95 do you need to be?
I-95 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 48% of East Walpole sits under tree canopy (heavier than most cities) and roughly 28% 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.

Airport Noise
General Edward Lawrence Logan International (BOS) sits northeast of East Walpole. The U.S. Department of Transportation measures aviation noise around this airport directly, and the model uses those federal measurements rather than synthetic predictions.
Blocks under the approach and departure paths carry combined road-plus-aviation noise, with some exceeding 75 dBA on the map's Overall layer. Blocks on the opposite side of East Walpole, particularly to the southwest, show no measurable aviation contribution. Use the Aviation toggle on the map above to isolate the airport's footprint.
How Noise Is Distributed Across East Walpole
The bar chart below shows the share of East Walpole residents in each noise band. About 59% of residents live below the EPA's 55 dBA threshold, and roughly 14% live in blocks above 60 dBA. Long-term exposure in that range is linked to elevated stress hormones and cardiovascular risk.
How East Walpole Compares
East Walpole sits at the louder end of the spectrum. Below: how East Walpole's average outdoor noise and share of residents above the EPA threshold compare with Avon, Sherborn, Foxborough, and Waban.
Average noise level (dBA)
East Walpole's 55.2 dBA pop-weighted average is at the louder end of the spectrum. Massachusetts as a whole averages 54.3 dBA and the U.S. averages 52.0 dBA. Both are lower than East Walpole because most of either area is rural land away from major roads.
Share of residents above 55 dBA
About 33.9% of East Walpole 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, 43.3% of East Walpole'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 East Walpole
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 I-95 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 48% of East Walpole is under tree cover (heavier than most 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.
Airport noise is directional. General Edward Lawrence Logan International's approach paths concentrate aviation noise to the northeast. Neighborhoods to the southwest of downtown show no measurable contribution from the airport.
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.
