This map shows modeled outdoor noise across Glenview Nas 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 5,105 Glenview Nas residents, or 36.8%, live above that level. By land area, 39.4% of Glenview Nas is above 55 dBA.

Noise by Part of Glenview Nas
Average noise levels for Glenview Nas residents, grouped by direction from the center of Glenview Nas. Central Glenview Nas carries the highest population-weighted average; Southern Glenview Nas carries the lowest. Just 20% of residents in Southern Glenview Nas live in blocks above the EPA's 55 dBA threshold, about half the share in Central Glenview Nas.
Central Glenview Nas
56% of people above 55 dBA
Eastern Glenview Nas
29% of people above 55 dBA
Northern Glenview Nas
39% of people above 55 dBA
Southern Glenview Nas
20% of people above 55 dBA
Western Glenview Nas
52% of people above 55 dBA
Central Glenview Nas sounds about 75% louder than Southern Glenview Nas to the human ear, a 8.1 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.
Loudest Road Corridors
The model evaluates every road in Glenview Nas using federal traffic counts, posted speeds, heavy-truck ratios, and pavement type. The source level shown is the modeled noise at the road centerline, where it is loudest. Noise drops with distance, faster in vegetated areas and slower over open pavement.
How far back from West Lake Ave do you need to be?
West Lake Ave produces an estimated 59 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 11% of Glenview Nas sits under tree canopy (lighter than most cities) and roughly 52% 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 Glenview Nas. 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
Chicago O'Hare International (ORD) sits southwest of Glenview Nas. 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 Glenview Nas, particularly to the northeast, show no measurable aviation contribution. Use the Aviation toggle on the map above to isolate the airport's footprint.
How Noise Is Distributed Across Glenview Nas
The bar chart below shows the share of Glenview Nas residents in each noise band. About 57% 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 Glenview Nas Compares
Glenview Nas sits at the quieter end of the spectrum. Below: how Glenview Nas's average outdoor noise and share of residents above the EPA threshold compare with Prospect Heights, Winnetka, Wood Dale, and Franklin Park.
Average noise level (dBA)
Glenview Nas's 55.6 dBA pop-weighted average is at the quieter end of the spectrum. Illinois as a whole averages 52.6 dBA and the U.S. averages 52.0 dBA. Both are lower than Glenview Nas because most of either area is rural land away from major roads.
Share of residents above 55 dBA
About 36.8% of Glenview Nas 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, 39.4% of Glenview Nas'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 Glenview Nas
- 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 West Lake Ave 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 11% of Glenview Nas is under tree cover (lighter than most cities), 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 southwest. Neighborhoods to the northeast 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.
Federal datasets used:
FHWA Highway Performance Monitoring System: road geometry, traffic counts, lane configuration
U.S. DoT Bureau of Transportation Statistics National Transportation Noise Map: aviation and rail noise, road calibration ground truth
USGS / MRLC National Land Cover Database: land cover and impervious surface coverage
USDA Forest Service Tree Canopy Cover: vegetation density for sound propagation
U.S. Census Bureau TIGER/Line: block-level geography and population
U.S. EPA Levels Document: 55 dBA outdoor reference level
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.
