QuietLoud
Western Dayton-Campbell Historic District sounds about 36% louder than Eastern Dayton-Campbell Historic District to the human ear, a 4.4 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 High St do you need to be?
High St produces an estimated 66 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 12% of Dayton-Campbell Historic District sits under tree canopy (about average for neighborhoods) and roughly 57% 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 Dayton-Campbell Historic District. 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 Dayton-Campbell Historic District
The bar chart below shows the share of Dayton-Campbell Historic District residents in each noise band. About 21% of residents live below the EPA's 55 dBA threshold, and roughly 16% live in blocks above 60 dBA. Long-term exposure in that range is linked to elevated stress hormones and cardiovascular risk.
How Dayton-Campbell Historic District Compares
Dayton-Campbell Historic District sits at the louder end of the spectrum. Below: how Dayton-Campbell Historic District's average outdoor noise and share of residents above the EPA threshold compare with Hamilton Main Street Historic District, Pleasant Run Farm, Northbrook, and Groesbeck.
Average noise level (dBA)
Dayton-Campbell Historic District's 57.5 dBA pop-weighted average is at the louder end of the spectrum. Ohio as a whole averages 51.1 dBA and the U.S. averages 52.0 dBA. Both are lower than Dayton-Campbell Historic District because most of either area is rural land away from major roads.
Share of residents above 55 dBA
About 71.6% of Dayton-Campbell Historic District 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, 79.2% of Dayton-Campbell Historic District's footprint sits above 55 dBA, against a Ohio average of 26.4% and a national average of 28.1%.
What This Means if You're Moving to Dayton-Campbell Historic District
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 High St 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 12% of Dayton-Campbell Historic District is under tree cover (about average for neighborhoods), and the dominant land cover is medium-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.
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.
