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 6,697 Old Fourth Ward residents, or 47.5%, live above that level. By land area, 52.0% of Old Fourth Ward is above 55 dBA.
Average noise levels for Old Fourth Ward residents, grouped by direction from the center of Old Fourth Ward. Western Old Fourth Ward carries the highest population-weighted average; Northern Old Fourth Ward carries the lowest. Just 41% of residents in Northern Old Fourth Ward live in blocks above the EPA's 55 dBA threshold, about two-thirds of the share in Western Old Fourth Ward.

QuietLoud
Western Old Fourth Ward sounds about 66% louder than Northern Old Fourth Ward to the human ear, a 7.3 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 Ralph Mcgill Blvd Ne; do you need to be?
Ralph Mcgill Blvd Ne; 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 11% of Old Fourth Ward sits under tree canopy (lighter than most neighborhoods) and roughly 68% 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 Old Fourth Ward. 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.
Airport Noise
Hartsfield/Jackson Atlanta International (ATL) sits south of Old Fourth Ward. The U.S. Department of Transportation measures aviation noise around this airport directly, 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 75 dBA on the map's Overall layer. Blocks on the opposite side of Old Fourth Ward, particularly to the north, show no measurable aviation contribution. Use the Aviation toggle on the map above to isolate the airport's footprint.
How Noise Is Distributed Across Old Fourth Ward
The bar chart below shows the share of Old Fourth Ward residents in each noise band. About 43% of residents live below the EPA's 55 dBA threshold, and roughly 17% live in blocks above 60 dBA. Long-term exposure in that range is linked to elevated stress hormones and cardiovascular risk.
How Old Fourth Ward Compares
Old Fourth Ward sits at the louder end of the spectrum. Below: how Old Fourth Ward's average outdoor noise and share of residents above the EPA threshold compare with Downtown, Virginia-Highland, Grove Park, and Edgewood-Kirkwood.
Average noise level (dBA)
Old Fourth Ward's 56.3 dBA pop-weighted average is at the louder end of the spectrum. Georgia as a whole averages 51.0 dBA and the U.S. averages 52.0 dBA. Both are lower than Old Fourth Ward because most of either area is rural land away from major roads.
Share of residents above 55 dBA
About 47.5% of Old Fourth Ward 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, 52.0% of Old Fourth Ward's footprint sits above 55 dBA, against a Georgia average of 22.6% and a national average of 28.1%.
What This Means if You're Moving to Old Fourth Ward
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 Ralph Mcgill Blvd Ne; 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 11% of Old Fourth Ward is under tree cover (lighter than most 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.
Airport noise is directional. Hartsfield/Jackson Atlanta International's approach paths concentrate aviation noise to the south. Neighborhoods to the north 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.
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.
