This map shows modeled outdoor noise across Glencove 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 3,477 Glencove residents, or 37.9%, live above that level. By land area, 37.6% of Glencove is above 55 dBA.

Noise by Part of Glencove
Average noise levels for Glencove residents, grouped by direction from the center of Glencove. The highest population-weighted average is in southwestern Glencove; the lowest is in southeastern Glencove, where just 6% of residents live in blocks above the EPA's 55 dBA threshold, a fifth of the share in the loudest section.
Southwestern Glencove
64% of people above 55 dBA
Western Glencove
58% of people above 55 dBA
Northern Glencove
48% of people above 55 dBA
Eastern Glencove
16% of people above 55 dBA
Southeastern Glencove
6% of people above 55 dBA
To the human ear, noise in southwestern Glencove sounds about 382% louder than in southeastern Glencove, a 22.7 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 I-780 do you need to be?
I-780 produces an estimated 77 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.
Calculated from the model's calibrated attenuation formula. About 7% of Glencove sits under tree canopy (lighter 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.
