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 2,188 Cedar-Isles-Dean residents, or 56.9%, live above that level. By land area, 73.0% of Cedar-Isles-Dean is above 55 dBA.
Average noise levels for Cedar-Isles-Dean residents, grouped by direction from the center of Cedar-Isles-Dean. Western Cedar-Isles-Dean carries the highest population-weighted average; Central Cedar-Isles-Dean carries the lowest. Just 44% of residents in Central Cedar-Isles-Dean live in blocks above the EPA's 55 dBA threshold, about half the share in Western Cedar-Isles-Dean.

QuietLoud
Western Cedar-Isles-Dean sounds about 120% louder than Central Cedar-Isles-Dean to the human ear, a 11.4 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 Alley do you need to be?
Alley produces an estimated 55 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.

Soft rainfall
Calculated from the model's calibrated attenuation formula. About 17% of Cedar-Isles-Dean sits under tree canopy (about average for neighborhoods) and roughly 46% 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 Cedar-Isles-Dean. 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
Minneapolis-St Paul International/Wold-Chamberlain (MSP) sits southeast of Cedar-Isles-Dean. 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 Cedar-Isles-Dean, particularly to the northwest, show no measurable aviation contribution. Use the Aviation toggle on the map above to isolate the airport's footprint.
How Noise Is Distributed Across Cedar-Isles-Dean
The bar chart below shows the share of Cedar-Isles-Dean residents in each noise band. About 30% 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 Cedar-Isles-Dean Compares
Cedar-Isles-Dean sits the lowest among the peer group. Below: how Cedar-Isles-Dean's average outdoor noise and share of residents above the EPA threshold compare with Midtown Phillips, Folwell, Northrup, and Victory.
Average noise level (dBA)
Cedar-Isles-Dean's 57.7 dBA pop-weighted average is the lowest among the peer group. Minnesota as a whole averages 53.6 dBA and the U.S. averages 52.0 dBA. Both are lower than Cedar-Isles-Dean because most of either area is rural land away from major roads.
Share of residents above 55 dBA
About 56.9% of Cedar-Isles-Dean residents live in blocks where outdoor levels exceed the EPA's 55 dBA threshold. That's fewer than any of its peer group. Measured by land area instead, 73.0% of Cedar-Isles-Dean's footprint sits above 55 dBA, against a Minnesota average of 31.0% and a national average of 28.1%.
What This Means if You're Moving to Cedar-Isles-Dean
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 Alley 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 17% of Cedar-Isles-Dean is under tree cover (about average for 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. Minneapolis-St Paul International/Wold-Chamberlain's approach paths concentrate aviation noise to the southeast. Neighborhoods to the northwest 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.
