This map shows modeled outdoor noise across Lake Carmel 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 1,103 Lake Carmel residents, or 18.2%, live above that level. By land area, 23.9% of Lake Carmel is above 55 dBA.

Noise by Part of Lake Carmel
Average noise levels for Lake Carmel residents, grouped by direction from the center of Lake Carmel. Northern Lake Carmel carries the highest population-weighted average; Southern Lake Carmel carries the lowest. Just 12% of residents in Southern Lake Carmel live in blocks above the EPA's 55 dBA threshold, about two-thirds of the share in Northern Lake Carmel.

Western Lake Carmel

Northern Lake Carmel sounds about 30% louder than Southern Lake Carmel to the human ear, a 3.8 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 Towners Rd do you need to be?
Towners Rd 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 64% of Lake Carmel sits under tree canopy (much heavier than most cities) and roughly 10% 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.
