This map shows modeled outdoor noise across Carver 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 789 Carver residents, or 26.8%, live above that level. By land area, 27.1% of Carver is above 55 dBA.

Noise by Part of Carver
Average noise levels for Carver residents, grouped by direction from the center of Carver. The highest population-weighted average is in northern Carver; the lowest is in southeastern Carver, where just 16% of residents live in blocks above the EPA's 55 dBA threshold, about two-thirds of the share in the loudest section.
Northern Carver
32% of people above 55 dBA
Northwestern Carver
28% of people above 55 dBA
Central Carver
25% of people above 55 dBA
Southwestern Carver
17% of people above 55 dBA
Southeastern Carver
16% of people above 55 dBA
To the human ear, noise in northern Carver sounds about 24% louder than in southeastern Carver, a 3.1 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 Amos St do you need to be?
Amos St produces an estimated 55 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 35% of Carver sits under tree canopy (much heavier than most neighborhoods) and roughly 31% 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.
