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 2,423 North Mayfair residents, or 83.2%, live above that level. By land area, 84.4% of North Mayfair is above 55 dBA.

Noise by Part of North Mayfair
Average noise levels for North Mayfair residents, grouped by direction from the center of North Mayfair. The highest population-weighted average is in western North Mayfair; the lowest is in eastern North Mayfair, where just 66% of residents live in blocks above the EPA's 55 dBA threshold, three-quarters of the share in the loudest section.

To the human ear, noise in western North Mayfair sounds about 58% louder than in eastern North Mayfair, a 6.6 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 67 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 7% of North Mayfair sits under tree canopy (lighter than most neighborhoods) and roughly 70% 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
Chicago O'Hare International (ORD) sits west of North Mayfair. 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 50 dBA on the map's Overall layer. Blocks on the opposite side of North Mayfair, particularly to the east, show no measurable aviation contribution. Use the Aviation toggle on the map above to isolate the airport's footprint.
How Noise Is Distributed Across North Mayfair
The bar chart below shows the share of North Mayfair residents in each noise band. About 7% of residents live below the EPA's 55 dBA threshold, and roughly 14% live in blocks above 60 dBA. Long-term exposure in that range is linked to elevated stress hormones and cardiovascular risk.
How North Mayfair Compares
North Mayfair sits the highest among the peer group. Below: how North Mayfair's average outdoor noise and share of residents above the EPA threshold compare with Schorsch, Roscoe Village, Montrose, and Ravenswood Gardens.
Average noise level (dBA)
North Mayfair's 57.9 dBA pop-weighted average is the highest among the peer group. Illinois as a whole averages 52.6 dBA and the U.S. averages 52.0 dBA. Both are lower than North Mayfair because most of either area is rural land away from major roads.
Share of residents above 55 dBA
About 83.2% of North Mayfair 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, 84.4% of North Mayfair's footprint sits above 55 dBA, against a Illinois average of 29.2% and a national average of 28.1%.
What This Means if You're Moving to North Mayfair
- 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 7% of North Mayfair is under tree cover (lighter than most 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. Chicago O'Hare International's approach paths concentrate aviation noise to the west. Neighborhoods to the east of downtown show no measurable contribution from the airport.
