This map shows modeled outdoor noise across Bonneville Hills 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 1,614 Bonneville Hills residents, or 56.1%, live above that level. By land area, 56.5% of Bonneville Hills is above 55 dBA.

Noise by Part of Bonneville Hills
Average noise levels for Bonneville Hills residents, grouped by direction from the center of Bonneville Hills. Eastern Bonneville Hills carries the highest population-weighted average; Northern Bonneville Hills carries the lowest. Just 48% of residents in Northern Bonneville Hills live in blocks above the EPA's 55 dBA threshold, about half the share in Eastern Bonneville Hills.

Normal conversation an arm’s length away
Eastern Bonneville Hills sounds about 84% louder than Northern Bonneville Hills to the human ear, a 8.8 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 73 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 14% of Bonneville Hills sits under tree canopy (about average for neighborhoods) and roughly 44% 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 Bonneville Hills. 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 Bonneville Hills, 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 Bonneville Hills
The bar chart below shows the share of Bonneville Hills residents in each noise band. About 29% of residents live below the EPA's 55 dBA threshold, and roughly 22% live in blocks above 60 dBA. Long-term exposure in that range is linked to elevated stress hormones and cardiovascular risk.
How Bonneville Hills Compares
Bonneville Hills sits at the louder end of the spectrum. Below: how Bonneville Hills's average outdoor noise and share of residents above the EPA threshold compare with Wasatch Hollow, Yalecrest, Jordan Meadows, and 9th and 9th.
Average noise level (dBA)
Bonneville Hills's 57.3 dBA pop-weighted average is at the louder end of the spectrum. Utah as a whole averages 53.1 dBA and the U.S. averages 52.0 dBA. Both are lower than Bonneville Hills because most of either area is rural land away from major roads.
Share of residents above 55 dBA
About 56.1% of Bonneville Hills 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, 56.5% of Bonneville Hills'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 Bonneville Hills
- 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 14% of Bonneville Hills is under tree cover (about average for 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.
- 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.
