This map shows modeled outdoor noise across North End at 100-meter resolution, combining road, aviation, and rail sources. Green areas measure below 45 dBA. Orange and red exceed the EPA's 55 dBA outdoor threshold linked to long-term health effects. Use the layer toggles to view each source on its own or all together.

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 1,507 North End residents, or 39.9%, live above that level. By land area, 49.8% of North End is above 55 dBA.

Noise by Part of North End
Average noise levels for North End residents, grouped by direction from the center of North End. The highest population-weighted average is in southern North End; the lowest is in eastern North End, where just 11% of residents live in blocks above the EPA's 55 dBA threshold, a fifth of the share in the loudest section.

To the human ear, noise in southern North End sounds about 201% louder than in eastern North End, a 15.9 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 78 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 34% of North End sits under tree canopy (much heavier than most neighborhoods) and roughly 32% 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 North End. 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 North End
The bar chart below shows the share of North End residents in each noise band. About 40% of residents live below the EPA's 55 dBA threshold, and roughly 30% live in blocks above 60 dBA. Long-term exposure in that range is linked to elevated stress hormones and cardiovascular risk.
How North End Compares
North End sits at the quieter end of the spectrum. Below: how North End's average outdoor noise and share of residents above the EPA threshold compare with Nashua Historic District, Mine Falls Park, Downtown Nashua, and crown-hill-nashua-nh.
Average noise level (dBA)
North End's 56.6 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 because most of either area is rural land away from major roads.
Share of residents above 55 dBA
About 39.9% of North End 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, 49.8% of North End'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
- 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 34% of North End 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.
