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 2,850 Cushing Square residents, or 54.7%, live above that level. By land area, 56.5% of Cushing Square is above 55 dBA.

Noise by Part of Cushing Square

Average noise levels for Cushing Square residents, grouped by direction from the center of Cushing Square. Northern Cushing Square carries the highest population-weighted average; Southern Cushing Square carries the lowest. Just 20% of residents in Southern Cushing Square live in blocks above the EPA's 55 dBA threshold, a third of the share in Northern Cushing Square.

QuietLoud

Northern Cushing Square sounds about 55% louder than Southern Cushing Square to the human ear, a 6.3 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 67 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 32% of Cushing Square sits under tree canopy (much heavier than most neighborhoods) 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.

Airport Noise

General Edward Lawrence Logan International (BOS) sits east of Cushing Square. 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 Cushing Square, particularly to the west, show no measurable aviation contribution. Use the Aviation toggle on the map above to isolate the airport's footprint.

How Noise Is Distributed Across Cushing Square

The bar chart below shows the share of Cushing Square residents in each noise band. About 45% of residents live below the EPA's 55 dBA threshold, and roughly 10% live in blocks above 60 dBA. Long-term exposure in that range is linked to elevated stress hormones and cardiovascular risk.

How Cushing Square Compares

Cushing Square sits at the quieter end of the spectrum. Below: how Cushing Square's average outdoor noise and share of residents above the EPA threshold compare with Bemis, Piety Corner, Waverley Square, and West Somerville.

Average noise level (dBA)

Cushing Square's 55.5 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 Cushing Square because most of either area is rural land away from major roads.

Share of residents above 55 dBA

About 54.7% of Cushing Square 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, 56.5% of Cushing Square'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 Cushing Square

  • 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 32% of Cushing Square is under tree cover (much heavier than most neighborhoods), and the dominant land cover is low-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.
  • Airport noise is directional. General Edward Lawrence Logan International's approach paths concentrate aviation noise to the east. Neighborhoods to the west 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.

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.
