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 2,713 Mount Pleasant residents, or 18.9%, live above that level. By land area, 26.8% of Mount Pleasant is above 55 dBA.
Average noise levels for Mount Pleasant residents, grouped by direction from the center of Mount Pleasant. Central Mount Pleasant carries the highest population-weighted average; Northern Mount Pleasant carries the lowest. Just 11% of residents in Northern Mount Pleasant live in blocks above the EPA's 55 dBA threshold, a third of the share in Central Mount Pleasant.

QuietLoud
Central Mount Pleasant sounds about 62% louder than Northern Mount Pleasant to the human ear, a 7.0 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-30 do you need to be?
I-30 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 32% of Mount Pleasant sits under tree canopy (about average for cities) and roughly 16% 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 Mount Pleasant. 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.
How Noise Is Distributed Across Mount Pleasant
The bar chart below shows the share of Mount Pleasant residents in each noise band. About 75% of residents live below the EPA's 55 dBA threshold, and roughly 10% live in blocks above 60 dBA. Long-term exposure in that range is linked to elevated stress hormones and cardiovascular risk.
How Mount Pleasant Compares
Mount Pleasant sits at the louder end of the spectrum. Below: how Mount Pleasant's average outdoor noise and share of residents above the EPA threshold compare with Gilmer, Pittsburg, Sulphur Springs, and Cookville.
Average noise level (dBA)
Mount Pleasant's 50.0 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 Mount Pleasant because most of either area is rural land away from major roads.
Share of residents above 55 dBA
About 18.9% of Mount Pleasant 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, 26.8% of Mount Pleasant'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 Mount Pleasant
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-30 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 32% of Mount Pleasant is under tree cover (about average for 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.
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.
