This map shows modeled outdoor noise across Malta 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 74 Malta residents, or 3.8%, live above that level. By land area, 17.8% of Malta is above 55 dBA.

Noise by Part of Malta
Average noise levels for Malta residents, grouped by direction from the center of Malta. Southern Malta carries the highest population-weighted average; Northern Malta carries the lowest. Just 0% of residents in Northern Malta live in blocks above the EPA's 55 dBA threshold, a fifth of the share in Southern Malta.
Eastern Malta
3% of people above 55 dBA
Northern Malta
0% of people above 55 dBA
Southern Malta
8% of people above 55 dBA
Southern Malta sounds about 173% louder than Northern Malta 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 Adirondack Northway do you need to be?
Adirondack Northway 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 soft rainfall.
Calculated from the model's calibrated attenuation formula. About 60% of Malta sits under tree canopy (heavier than most cities) and roughly 6% 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.
