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 5,985 37411 residents, or 37.3%, live above that level. By land area, 43.6% of 37411 is above 55 dBA.
Average noise levels for 37411 residents, grouped by direction from the center of 37411. Southern 37411 carries the highest population-weighted average; Northern 37411 carries the lowest. Just 22% of residents in Northern 37411 live in blocks above the EPA's 55 dBA threshold, about half the share in Southern 37411.

Southern 37411 sounds about 61% louder than Northern 37411 to the human ear, a 6.9 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 I-24 do you need to be?
I-24 produces an estimated 79 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 quiet suburban street at night.

Soft rainfall
Calculated from the model's calibrated attenuation formula. About 40% of 37411 sits under tree canopy (heavier than most zip codes) and roughly 21% 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
Lovell Field (CHA) sits east of 37411. 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 80 dBA on the map's Overall layer. Blocks on the opposite side of 37411, particularly to the west, show no measurable aviation contribution. Use the Aviation toggle on the map above to isolate the airport's footprint.
How Noise Is Distributed Across 37411
The bar chart below shows the share of 37411 residents in each noise band. About 68% of residents live below the EPA's 55 dBA threshold, and roughly 9% live in blocks above 60 dBA. Long-term exposure in that range is linked to elevated stress hormones and cardiovascular risk.
How 37411 Compares
37411 sits the highest among the peer group. Below: how 37411's average outdoor noise and share of residents above the EPA threshold compare with 37405, 37416, 37412, and 37377.
Average noise level (dBA)
37411's 54.0 dBA pop-weighted average is the highest among the peer group. Tennessee as a whole averages 49.2 dBA and the U.S. averages 52.0 dBA. Both are lower than 37411 because most of either area is rural land away from major roads.
Share of residents above 55 dBA
About 37.3% of 37411 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, 43.6% of 37411's footprint sits above 55 dBA, against a Tennessee average of 18.7% and a national average of 28.1%.
What This Means if You're Moving to 37411
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 I-24 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 40% of 37411 is under tree cover (heavier than most zip codes), 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. Lovell Field's approach paths concentrate aviation noise to the east. Neighborhoods to the west 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.
