This map shows modeled outdoor noise across Napanoch 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 432 Napanoch residents, or 15.5%, live above that level. By land area, 15.1% of Napanoch is above 55 dBA.

Noise by Part of Napanoch
Average noise levels for Napanoch residents, grouped by direction from the center of Napanoch. Southern Napanoch carries the highest population-weighted average; Western Napanoch carries the lowest. Just 0% of residents in Western Napanoch live in blocks above the EPA's 55 dBA threshold, a fifth of the share in Southern Napanoch.
Central Napanoch
15% of people above 55 dBA
Eastern Napanoch
16% of people above 55 dBA
Northern Napanoch
1% of people above 55 dBA
Southern Napanoch
23% of people above 55 dBA
Western Napanoch
0% of people above 55 dBA
Southern Napanoch sounds about 173% louder than Western Napanoch to the human ear, a 14.5 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 Ny 55 do you need to be?
Ny 55 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 44% of Napanoch sits under tree canopy (heavier than most cities) and roughly 34% 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.
