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 541 Cooper Park residents, or 17.3%, live above that level. By land area, 16.5% of Cooper Park is above 55 dBA.
Average noise levels for Cooper Park residents, grouped by direction from the center of Cooper Park. Southern Cooper Park carries the highest population-weighted average; Northern Cooper Park carries the lowest. Just 0% of residents in Northern Cooper Park live in blocks above the EPA's 55 dBA threshold, a fifth of the share in Southern Cooper Park.

QuietLoud
Southern Cooper Park sounds about 55% louder than Northern Cooper Park to the human ear, a 6.3 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 63 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 12% of Cooper Park sits under tree canopy (about average for neighborhoods) and roughly 57% 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
General Mitchell International (MKE) sits southeast of Cooper Park. 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 65 dBA on the map's Overall layer. Blocks on the opposite side of Cooper Park, 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 Cooper Park
The bar chart below shows the share of Cooper Park residents in each noise band. About 82% 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 Cooper Park Compares
Cooper Park sits the lowest among the peer group. Below: how Cooper Park's average outdoor noise and share of residents above the EPA threshold compare with Dineen Park, Sunset Heights, Silver Swan, and Columbus Park.
Average noise level (dBA)
Cooper Park's 54.0 dBA pop-weighted average is the lowest among the peer group. Wisconsin as a whole averages 53.0 dBA and the U.S. averages 52.0 dBA. Both are lower than Cooper Park because most of either area is rural land away from major roads.
Share of residents above 55 dBA
About 17.3% of Cooper Park 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, 16.5% of Cooper Park's footprint sits above 55 dBA, against a Wisconsin average of 29.6% and a national average of 28.1%.
What This Means if You're Moving to Cooper Park
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 12% of Cooper Park 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. General Mitchell International'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.
