This map shows modeled outdoor noise across La Vernia 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 419 La Vernia residents, or 3.6%, live above that level. By land area, 8.5% of La Vernia is above 55 dBA.

Noise by Part of La Vernia
Average noise levels for La Vernia residents, grouped by direction from the center of La Vernia. The highest population-weighted average is in northwestern La Vernia; the lowest is in western La Vernia, where just 0% of residents live in blocks above the EPA's 55 dBA threshold, a third of the share in the loudest section.
Northwestern La Vernia
2% of people above 55 dBA
Northeastern La Vernia
2% of people above 55 dBA
Southwestern La Vernia
1% of people above 55 dBA
Eastern La Vernia
1% of people above 55 dBA
Western La Vernia
0% of people above 55 dBA
To the human ear, noise in northwestern La Vernia sounds about 24% louder than in western La Vernia, 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 do you need to be?
produces an estimated 73 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 5% of La Vernia sits under tree canopy (much lighter 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.
