This map shows modeled outdoor noise across Redmont Park 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 958 Redmont Park residents, or 31.5%, live above that level. By land area, 42.4% of Redmont Park is above 55 dBA.

Noise by Part of Redmont Park
Average noise levels for Redmont Park residents, grouped by direction from the center of Redmont Park. The highest population-weighted average is in western Redmont Park; the lowest is in northeastern Redmont Park, where just 22% of residents live in blocks above the EPA's 55 dBA threshold, about half the share in the loudest section.

Quiet office to normal conversation
To the human ear, noise in western Redmont Park sounds about 120% louder than in northeastern Redmont Park, a 11.4 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 Cahaba Rd do you need to be?
Cahaba Rd produces an estimated 56 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 37% of Redmont Park sits under tree canopy (much heavier than most neighborhoods) and roughly 30% 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
Birmingham-Shuttlesworth International (BHM) sits north of Redmont Park. 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 Redmont Park, particularly to the south, show no measurable aviation contribution. Use the Aviation toggle on the map above to isolate the airport's footprint.
How Noise Is Distributed Across Redmont Park
The bar chart below shows the share of Redmont Park residents in each noise band. About 74% of residents live below the EPA's 55 dBA threshold, and roughly 5% live in blocks above 60 dBA. Long-term exposure in that range is linked to elevated stress hormones and cardiovascular risk.
How Redmont Park Compares
Redmont Park sits at the quieter end of the spectrum. Below: how Redmont Park's average outdoor noise and share of residents above the EPA threshold compare with Crestline, Forest Park, Norwood, and South East Lake.
Average noise level (dBA)
Redmont Park's 53.2 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 Redmont Park because most of either area is rural land away from major roads.
Share of residents above 55 dBA
About 31.5% of Redmont Park 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, 42.4% of Redmont Park'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 Redmont Park
- 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 Cahaba 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 37% of Redmont Park is under tree cover (much heavier than most neighborhoods), and the dominant land cover is low-density developed open space. 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. Birmingham-Shuttlesworth International's approach paths concentrate aviation noise to the north. Neighborhoods to the south of downtown show no measurable contribution from the airport.
