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 2,166 North End Manchester residents, or 40.5%, live above that level. By land area, 43.7% of North End Manchester is above 55 dBA.

Noise by Part of North End Manchester

Average noise levels for North End Manchester residents, grouped by direction from the center of North End Manchester. The highest population-weighted average is in southwestern North End Manchester; the lowest is in southeastern North End Manchester, where just 14% of residents live in blocks above the EPA's 55 dBA threshold, about half the share in the loudest section.

QuietLoud

To the human ear, noise in southwestern North End Manchester sounds about 78% louder than in southeastern North End Manchester, a 8.3 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 River Rd do you need to be?

River Rd produces an estimated 58 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 36% of North End Manchester sits under tree canopy (much heavier than most neighborhoods) and roughly 37% 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

Manchester Boston Regional (MHT) sits south of North End Manchester. The U.S. Department of Transportation models aviation noise around this airport from federal traffic data, 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 55 dBA on the map's Overall layer. Blocks on the opposite side of North End Manchester, particularly to the north, show no measurable aviation contribution. Use the Aviation toggle on the map above to isolate the airport's footprint.

How Noise Is Distributed Across North End Manchester

The bar chart below shows the share of North End Manchester residents in each noise band. About 56% of residents live below the EPA's 55 dBA threshold, and roughly 26% live in blocks above 60 dBA. Long-term exposure in that range is linked to elevated stress hormones and cardiovascular risk.

How North End Manchester Compares

North End Manchester sits at the quieter end of the spectrum. Below: how North End Manchester's average outdoor noise and share of residents above the EPA threshold compare with Wellington, Straw-Smyth, Rimmon Heights, and Somerville.

Average noise level (dBA)

North End Manchester's 56.9 dBA pop-weighted average is at the quieter end of the spectrum. New Hampshire as a whole averages 48.7 dBA and the U.S. averages 52.0 dBA. Both are lower than North End Manchester because most of either area is rural land away from major roads.

Share of residents above 55 dBA

About 40.5% of North End Manchester 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, 43.7% of North End Manchester's footprint sits above 55 dBA, against a New Hampshire average of 18.7% and a national average of 28.1%.

What This Means if You're Moving to North End Manchester

  • 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 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 36% of North End Manchester 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. Manchester Boston Regional's approach paths concentrate aviation noise to the south. Neighborhoods to the north 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.
