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 1,068 Belview Heights residents, or 42.7%, live above that level. By land area, 44.7% of Belview Heights is above 55 dBA.
Average noise levels for Belview Heights residents, grouped by direction from the center of Belview Heights. Eastern Belview Heights carries the highest population-weighted average; Western Belview Heights carries the lowest. Just 33% of residents in Western Belview Heights live in blocks above the EPA's 55 dBA threshold, about two-thirds of the share in Eastern Belview Heights.

QuietLoud
Eastern Belview Heights sounds about 33% louder than Western Belview Heights to the human ear, a 4.1 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 Old US Hwy 78 do you need to be?
Old US Hwy 78 produces an estimated 59 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 27% of Belview Heights sits under tree canopy (heavier than most neighborhoods) and roughly 35% 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 Belview Heights
The bar chart below shows the share of Belview Heights residents in each noise band. About 62% of residents live below the EPA's 55 dBA threshold, and roughly 4% live in blocks above 60 dBA. Long-term exposure in that range is linked to elevated stress hormones and cardiovascular risk.
How Belview Heights Compares
Belview Heights sits at the quieter end of the spectrum. Below: how Belview Heights's average outdoor noise and share of residents above the EPA threshold compare with Arlington, Norwood, smithfield-estates-birmingham-al, and Forest Park.
Average noise level (dBA)
Belview Heights's 53.5 dBA pop-weighted average is at the quieter end of the spectrum. Alabama as a whole averages 49.0 dBA and the U.S. averages 52.0 dBA. Both are lower than Belview Heights because most of either area is rural land away from major roads.
Share of residents above 55 dBA
About 42.7% of Belview Heights 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, 44.7% of Belview Heights's footprint sits above 55 dBA, against a Alabama average of 20.0% and a national average of 28.1%.
What This Means if You're Moving to Belview Heights
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 Old US Hwy 78 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 27% of Belview Heights is under tree cover (heavier than most 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.
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.
