Normal conversation an arm’s length away
Northern Central City Liberty Wells sounds about 39% louder than Southern Central City Liberty Wells to the human ear, a 4.8 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 do you need to be?
produces an estimated 74 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 5% of Central City Liberty Wells sits under tree canopy (lighter than most neighborhoods) and roughly 58% 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
Salt Lake City International (SLC) sits northwest of Central City Liberty Wells. 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 Central City Liberty Wells, particularly to the southeast, show no measurable aviation contribution. Use the Aviation toggle on the map above to isolate the airport's footprint.
How Noise Is Distributed Across Central City Liberty Wells
The bar chart below shows the share of Central City Liberty Wells residents in each noise band. About 38% 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 Central City Liberty Wells Compares
Central City Liberty Wells sits at the quieter end of the spectrum. Below: how Central City Liberty Wells's average outdoor noise and share of residents above the EPA threshold compare with Downtown, 9th and 9th, Fairpark, and Barrington Park.
Average noise level (dBA)
Central City Liberty Wells's 55.8 dBA pop-weighted average is at the quieter end of the spectrum. Utah as a whole averages 53.1 dBA and the U.S. averages 52.0 dBA. Both are lower than Central City Liberty Wells because most of either area is rural land away from major roads.
Share of residents above 55 dBA
About 52.7% of Central City Liberty Wells 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, 53.7% of Central City Liberty Wells's footprint sits above 55 dBA, against a Utah average of 25.8% and a national average of 28.1%.
What This Means if You're Moving to Central City Liberty Wells
- 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 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 5% of Central City Liberty Wells 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. Salt Lake City International's approach paths concentrate aviation noise to the northwest. Neighborhoods to the southeast of downtown show no measurable contribution from the airport.
