This map shows modeled outdoor noise across South Ogden 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 5,300 South Ogden residents, or 36.3%, live above that level. By land area, 39.6% of South Ogden is above 55 dBA.

Noise by Part of South Ogden
Average noise levels for South Ogden residents, grouped by direction from the center of South Ogden. The highest population-weighted average is in western South Ogden; the lowest is in southwestern South Ogden, where just 26% of residents live in blocks above the EPA's 55 dBA threshold, three-quarters of the share in the loudest section.

Quiet office to normal conversation
To the human ear, noise in western South Ogden sounds about 32% louder than in southwestern South Ogden, a 4.0 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 70 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 9% of South Ogden sits under tree canopy (lighter than most cities) and roughly 42% 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 south of South Ogden. 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 45 dBA on the map's Overall layer. Blocks on the opposite side of South Ogden, 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 South Ogden
The bar chart below shows the share of South Ogden residents in each noise band. About 64% of residents live below the EPA's 55 dBA threshold, and roughly 4% live in blocks above 60 dBA. Long-term exposure in that range is linked to elevated stress hormones and cardiovascular risk.
How South Ogden Compares
South Ogden sits at the louder end of the spectrum. Below: how South Ogden's average outdoor noise and share of residents above the EPA threshold compare with West Haven, Washington Terrace, Clinton, and North Ogden.
Average noise level (dBA)
South Ogden's 53.7 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 South Ogden because most of either area is rural land away from major roads.
Share of residents above 55 dBA
About 36.3% of South Ogden 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, 39.6% of South Ogden'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 South Ogden
- 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 9% of South Ogden is under tree cover (lighter than most cities), 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 south. Neighborhoods to the north of downtown show no measurable contribution from the airport.
