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 40 Mount Holly residents, or 3.8%, live above that level. By land area, 6.8% of Mount Holly is above 55 dBA.

See how noise in Mount Holly compares to similar-sized cities.
Southern Mount Holly sounds about 0% louder than Northern Mount Holly to the human ear, a 0.0 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.

Loudest Road Corridors
The model evaluates every road in Mount Holly 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 Lindale Mt Holly Rd do you need to be?
Lindale Mt Holly Rd produces an estimated 55 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 9% of Mount Holly sits under tree canopy (lighter than most cities) and roughly 10% 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.
How Noise Is Distributed Across Mount Holly
The bar chart below shows the share of Mount Holly residents in each noise band. About 98% 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 Mount Holly Compares
Mount Holly sits at the quieter end of the spectrum. Below: how Mount Holly's average outdoor noise and share of residents above the EPA threshold compare with Ogden, Dodds, Senior, and Harveysburg.
Average noise level (dBA)
Mount Holly's 42.5 dBA pop-weighted average is at the quieter end of the spectrum. Ohio as a whole averages 51.1 dBA and the U.S. averages 52.0 dBA. Both are lower than Mount Holly because most of either area is rural land away from major roads.
Share of residents above 55 dBA
About 3.8% of Mount Holly 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, 6.8% of Mount Holly'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 Mount Holly
- 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 Lindale Mt Holly Rd 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 9% of Mount Holly is under tree cover (lighter than most cities), and the dominant land cover is cultivated cropland. 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.
