This map shows modeled outdoor noise across Oak Grove 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 2,326 Oak Grove residents, or 37.7%, live above that level. By land area, 43.4% of Oak Grove is above 55 dBA.

Noise by Part of Oak Grove
Average noise levels for Oak Grove residents, grouped by direction from the center of Oak Grove. Eastern Oak Grove carries the highest population-weighted average; Western Oak Grove carries the lowest. Just 23% of residents in Western Oak Grove live in blocks above the EPA's 55 dBA threshold, about half the share in Eastern Oak Grove.
Central Oak Grove
28% of people above 55 dBA
Eastern Oak Grove
58% of people above 55 dBA
Northern Oak Grove
27% of people above 55 dBA
Southern Oak Grove
37% of people above 55 dBA
Western Oak Grove
23% of people above 55 dBA
Eastern Oak Grove sounds about 43% louder than Western Oak Grove to the human ear, a 5.2 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.
Loudest Road Corridors
The model evaluates every road in Oak Grove using federal traffic counts, posted speeds, heavy-truck ratios, and pavement type. The source level shown is the modeled noise at the road centerline, where it is loudest. Noise drops with distance, faster in vegetated areas and slower over open pavement.
How far back from Schoolcraft Fwy do you need to be?
Schoolcraft Fwy produces an estimated 75 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 14% of Oak Grove sits under tree canopy (about average for neighborhoods) and roughly 37% 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
Springfield-Branson Ntl (SGF) sits northwest of Oak Grove. 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 Oak Grove, particularly to the southeast, show no measurable aviation contribution. Use the Aviation toggle on the map above to isolate the airport's footprint.
How Noise Is Distributed Across Oak Grove
The bar chart below shows the share of Oak Grove residents in each noise band. About 49% 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 Oak Grove Compares
Oak Grove sits the lowest among the peer group. Below: how Oak Grove's average outdoor noise and share of residents above the EPA threshold compare with Southern Hills, Seminole Holland, Bingham, and Phelps.
Average noise level (dBA)
Oak Grove's 54.7 dBA pop-weighted average is the lowest among the peer group. Missouri as a whole averages 53.9 dBA and the U.S. averages 52.0 dBA. Both are lower than Oak Grove because most of either area is rural land away from major roads.
Share of residents above 55 dBA
About 37.7% of Oak 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, 43.4% of Oak Grove's footprint sits above 55 dBA, against a Missouri average of 32.5% and a national average of 28.1%.
What This Means if You're Moving to Oak 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 Schoolcraft Fwy 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 14% of Oak Grove is under tree cover (about average for neighborhoods), 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. Springfield-Branson Ntl's approach paths concentrate aviation noise to the northwest. Neighborhoods to the southeast 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.
Federal datasets used:
FHWA Highway Performance Monitoring System: road geometry, traffic counts, lane configuration
U.S. DoT Bureau of Transportation Statistics National Transportation Noise Map: aviation and rail noise, road calibration ground truth
USGS / MRLC National Land Cover Database: land cover and impervious surface coverage
USDA Forest Service Tree Canopy Cover: vegetation density for sound propagation
U.S. Census Bureau TIGER/Line: block-level geography and population
U.S. EPA Levels Document: 55 dBA outdoor reference level
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.
