Eastern Hill Farms-University Neighborh sounds about 22% louder than Western Hill Farms-University Neighborh to the human ear, a 2.9 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 29% of Hill Farms-University Neighborh sits under tree canopy (heavier than most neighborhoods) and roughly 34% 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
Dane County Regional/Truax Field (MSN) sits northeast of Hill Farms-University Neighborh. 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 55 dBA on the map's Overall layer. Blocks on the opposite side of Hill Farms-University Neighborh, particularly to the southwest, show no measurable aviation contribution. Use the Aviation toggle on the map above to isolate the airport's footprint.
How Noise Is Distributed Across Hill Farms-University Neighborh
The bar chart below shows the share of Hill Farms-University Neighborh residents in each noise band. About 42% of residents live below the EPA's 55 dBA threshold, and roughly 0% live in blocks above 60 dBA. Long-term exposure in that range is linked to elevated stress hormones and cardiovascular risk.
How Hill Farms-University Neighborh Compares
Hill Farms-University Neighborh sits at the quieter end of the spectrum. Below: how Hill Farms-University Neighborh's average outdoor noise and share of residents above the EPA threshold compare with Midvale Heights, Dudgeon-Monroe, spring-harbor-madison-wi, and Sunset Village.
Average noise level (dBA)
Hill Farms-University Neighborh's 55.0 dBA pop-weighted average is at the quieter end of the spectrum. Wisconsin as a whole averages 53.0 dBA and the U.S. averages 52.0 dBA. Both are lower than Hill Farms-University Neighborh because most of either area is rural land away from major roads.
Share of residents above 55 dBA
About 38.6% of Hill Farms-University Neighborh 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, 38.3% of Hill Farms-University Neighborh'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 Hill Farms-University Neighborh
- 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 29% of Hill Farms-University Neighborh is under tree cover (heavier than most 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. Dane County Regional/Truax Field's approach paths concentrate aviation noise to the northeast. Neighborhoods to the southwest of downtown show no measurable contribution from the airport.
