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 144 College Station residents, or 54.3%, live above that level. By land area, 74.2% of College Station is above 55 dBA.
Average noise levels for College Station residents, grouped by direction from the center of College Station. Western College Station carries the highest population-weighted average; Central College Station carries the lowest. Just 43% of residents in Central College Station live in blocks above the EPA's 55 dBA threshold, about two-thirds of the share in Western College Station.

QuietLoud
Western College Station sounds about 10% louder than Central College Station to the human ear, a 1.4 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 I-440 do you need to be?
I-440 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 54% of College Station sits under tree canopy (heavier than most cities) and roughly 12% 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 College Station. 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
Bill And Hillary Clinton Ntl/Adams Field (LIT) sits north of College Station. 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 College Station, 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 College Station
The bar chart below shows the share of College Station residents in each noise band. About 32% of residents live below the EPA's 55 dBA threshold, and roughly 0% live in blocks above 60 dBA. Long-term exposure in that range is linked to elevated stress hormones and cardiovascular risk.
How College Station Compares
College Station sits the highest among the peer group. Below: how College Station's average outdoor noise and share of residents above the EPA threshold compare with Keo, Rose City, Toltec, and Vimy Ridge.
Average noise level (dBA)
College Station's 56.2 dBA pop-weighted average is the highest among the peer group. Arkansas as a whole averages 52.6 dBA and the U.S. averages 52.0 dBA. Both are lower than College Station because most of either area is rural land away from major roads.
Share of residents above 55 dBA
About 54.3% of College Station residents live in blocks where outdoor levels exceed the EPA's 55 dBA threshold. That's more than any of its peer group. Measured by land area instead, 74.2% of College Station's footprint sits above 55 dBA, against a Arkansas average of 29.9% and a national average of 28.1%.
What This Means if You're Moving to College Station
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 I-440 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 54% of College Station is under tree cover (heavier than most cities), and the dominant land cover is low-density developed open space. 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. Bill And Hillary Clinton Ntl/Adams Field's approach paths concentrate aviation noise to the north. Neighborhoods to the south of downtown show no measurable contribution from the airport.
Sources & Methodology
The BestNeighborhood noise model is calibrated against nearly one million federal ground-truth measurements across four states. Road noise is computed from segment-level federal traffic data and propagated outward using physics-based acoustic decay, with attenuation rates that depend on the surrounding land cover.
All inputs are published federal datasets. Block-level noise is computed by combining road, rail, and aviation sound sources in the energy domain, the same physics used in professional environmental noise assessments. Read the full methodology.
