This map shows modeled outdoor noise across White Island Shores 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 63 White Island Shores residents, or 8.5%, live above that level. By land area, 16.5% of White Island Shores is above 55 dBA.

Noise by Part of White Island Shores
Average noise levels for White Island Shores residents, grouped by direction from the center of White Island Shores. Southern White Island Shores carries the highest population-weighted average; Western White Island Shores carries the lowest. Just 5% of residents in Western White Island Shores live in blocks above the EPA's 55 dBA threshold, about half the share in Southern White Island Shores.
Eastern White Island Shores
6% of people above 55 dBA
Northern White Island Shores

Southern White Island Shores

Western White Island Shores
5% of people above 55 dBA
Southern White Island Shores sounds about 62% louder than Western White Island Shores to the human ear, a 7.0 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 Blue Star Memorial Hwy do you need to be?
Blue Star Memorial Hwy produces an estimated 75 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 73% of White Island Shores sits under tree canopy (much heavier than most cities) and roughly 7% 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.
