This map shows modeled outdoor noise across 75703 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 6,194 75703 residents, or 17.2%, live above that level. By land area, 20.8% of 75703 is above 55 dBA.

Noise by Part of 75703
Average noise levels for 75703 residents, grouped by direction from the center of 75703. Central 75703 carries the highest population-weighted average; Eastern 75703 carries the lowest. Just 14% of residents in Eastern 75703 live in blocks above the EPA's 55 dBA threshold, a fraction of the share in Central 75703.

Central 75703 sounds about 36% louder than Eastern 75703 to the human ear, a 4.4 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 W Loop 49 do you need to be?
W Loop 49 produces an estimated 67 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 36% of 75703 sits under tree canopy (heavier than most zip codes) and roughly 32% 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.
