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 57 Elmhurst residents, or 11.8%, live above that level. By land area, 37.3% of Elmhurst is above 55 dBA.
Average noise levels for Elmhurst residents, grouped by direction from the center of Elmhurst. Southern Elmhurst carries the highest population-weighted average; Eastern Elmhurst carries the lowest. Just 6% of residents in Eastern Elmhurst live in blocks above the EPA's 55 dBA threshold, about half the share in Southern Elmhurst.

QuietLoud
Southern Elmhurst sounds about 185% louder than Eastern Elmhurst to the human ear, a 15.1 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.
How far back from Fallen Trooper Mem Hwy do you need to be?
Fallen Trooper Mem Hwy produces an estimated 75 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 73% of Elmhurst sits under tree canopy (much heavier than most cities) and roughly 0% 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 Elmhurst. 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.
How Noise Is Distributed Across Elmhurst
The bar chart below shows the share of Elmhurst residents in each noise band. About 54% of residents live below the EPA's 55 dBA threshold, and roughly 46% live in blocks above 60 dBA. Long-term exposure in that range is linked to elevated stress hormones and cardiovascular risk.
How Elmhurst Compares
Elmhurst sits the highest among the peer group. Below: how Elmhurst's average outdoor noise and share of residents above the EPA threshold compare with Sterling, Daleville, Tooley Corners, and Milwaukee.
Average noise level (dBA)
Elmhurst's 54.5 dBA pop-weighted average is the highest among the peer group. Pennsylvania as a whole averages 52.9 dBA and the U.S. averages 52.0 dBA. Both are lower than Elmhurst because most of either area is rural land away from major roads.
Share of residents above 55 dBA
About 11.8% of Elmhurst 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, 37.3% of Elmhurst's footprint sits above 55 dBA, against a Pennsylvania average of 33.5% and a national average of 28.1%.
What This Means if You're Moving to Elmhurst
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 Fallen Trooper Mem Hwy 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 73% of Elmhurst is under tree cover (much heavier than most cities), and the dominant land cover is deciduous forest. 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.
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.
