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 112 Plum Grove residents, or 3.4%, live above that level. By land area, 1.8% of Plum Grove is above 55 dBA.
Average noise levels for Plum Grove residents, grouped by direction from the center of Plum Grove. Eastern Plum Grove carries the highest population-weighted average; Northern Plum Grove carries the lowest. Just 6% of residents in Northern Plum Grove live in blocks above the EPA's 55 dBA threshold, roughly the same as the share in Eastern Plum Grove.

QuietLoud
Eastern Plum Grove sounds about 20% louder than Northern Plum Grove to the human ear, a 2.6 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 64 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 40% of Plum Grove sits under tree canopy (about average for 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.

Airport Noise
George Bush Intcntl/Houston (IAH) sits southwest of Plum Grove. The U.S. Department of Transportation measures aviation noise around this airport directly, 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 75 dBA on the map's Overall layer. Blocks on the opposite side of Plum Grove, particularly to the northeast, show no measurable aviation contribution. Use the Aviation toggle on the map above to isolate the airport's footprint.
How Noise Is Distributed Across Plum Grove
The bar chart below shows the share of Plum Grove residents in each noise band. About 99% 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 Plum Grove Compares
Plum Grove sits the lowest among the peer group. Below: how Plum Grove's average outdoor noise and share of residents above the EPA threshold compare with Shenandoah, Walden Woods, Barrett, and Stilson.
Average noise level (dBA)
Plum Grove's 45.7 dBA pop-weighted average is the lowest among the peer group. Texas as a whole averages 50.8 dBA and the U.S. averages 52.0 dBA. Both are lower than Plum Grove because most of either area is rural land away from major roads.
Share of residents above 55 dBA
About 3.4% of Plum Grove residents live in blocks where outdoor levels exceed the EPA's 55 dBA threshold. That's fewer than any of its peer group. Measured by land area instead, 1.8% of Plum Grove'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 Plum Grove
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 40% of Plum Grove is under tree cover (about average for cities), and the dominant land cover is mixed forest. 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. George Bush Intcntl/Houston's approach paths concentrate aviation noise to the southwest. Neighborhoods to the northeast 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.
