This map shows modeled outdoor noise across 75233 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 3,829 75233 residents, or 31.6%, live above that level. By land area, 31.5% of 75233 is above 55 dBA.

Noise by Part of 75233
Average noise levels for 75233 residents, grouped by direction from the center of 75233. The highest population-weighted average is in southern 75233; the lowest is in central 75233, where just 22% of residents live in blocks above the EPA's 55 dBA threshold, about two-thirds of the share in the loudest section.

Quiet office to normal conversation
To the human ear, noise in southern 75233 sounds about 88% louder than in central 75233, a 9.1 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 69 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.

Soft rainfall
Calculated from the model's calibrated attenuation formula. About 19% of 75233 sits under tree canopy (about average for zip codes) and roughly 42% 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.

Rail Noise
Active freight rail runs through parts of 75233. For most blocks the rail-only contribution is small. Combined road-plus-rail noise rarely exceeds road noise on its own. The exceptions are the handful of blocks within roughly a quarter mile of the right-of-way during pass-through hours.
Use the Rail toggle on the map above to isolate rail's contribution from road and aviation.
Airport Noise
Dallas Love Field (DAL) sits north of 75233. The U.S. Department of Transportation models aviation noise around this airport from federal traffic data, and the model uses those federal measurements rather than synthetic predictions.
Blocks under the approach and departure paths carry combined road-plus-aviation noise, with some exceeding 55 dBA on the map's Overall layer. Blocks on the opposite side of 75233, particularly to the south, show no measurable aviation contribution. Use the Aviation toggle on the map above to isolate the airport's footprint.
How Noise Is Distributed Across 75233
The bar chart below shows the share of 75233 residents in each noise band. About 63% of residents live below the EPA's 55 dBA threshold, and roughly 8% live in blocks above 60 dBA. Long-term exposure in that range is linked to elevated stress hormones and cardiovascular risk.
How 75233 Compares
75233 sits at the louder end of the spectrum. Below: how 75233's average outdoor noise and share of residents above the EPA threshold compare with 75236, 75137, 75116, and 75219.
Average noise level (dBA)
75233's 52.9 dBA pop-weighted average is at the louder end of the spectrum. Texas as a whole averages 50.8 dBA and the U.S. averages 52.0 dBA. Both are lower than 75233 because most of either area is rural land away from major roads.
Share of residents above 55 dBA
About 31.6% of 75233 residents live in blocks where outdoor levels exceed the EPA's 55 dBA threshold. That's in the middle of its peer group. Measured by land area instead, 31.5% of 75233's footprint sits above 55 dBA, against a Texas average of 22.8% and a national average of 28.1%.
What This Means if You're Moving to 75233
- Distance from highways matters more than the neighborhood name. Two homes in the same zip code can differ by 20 dBA if one sits 100 meters from and the other 500 meters away. The model captures this at 100-meter resolution, so noise exposure changes block by block.
- Tree canopy can help reduce modeled noise exposure. Roughly 19% of 75233 is under tree cover (about average for zip codes), and the dominant land cover is low-intensity developed land. Both are measured from federal USDA Forest Service and USGS satellite imagery at 30-meter resolution. Streets with 60% or higher canopy show 3 to 5 dBA lower noise than comparable streets with bare ground or pavement, which is why the per-place decay rate above already accounts for it.
- Airport noise is directional. Dallas Love Field's approach paths concentrate aviation noise to the north. Neighborhoods to the south of downtown show no measurable contribution from the airport.
