This map shows modeled outdoor noise across West Side 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 8,300 West Side residents, or 64.4%, live above that level. By land area, 69.9% of West Side is above 55 dBA.

Noise by Part of West Side
Average noise levels for West Side residents, grouped by direction from the center of West Side. The highest population-weighted average is in southern West Side; the lowest is in northwestern West Side, where just 17% of residents live in blocks above the EPA's 55 dBA threshold, a fifth of the share in the loudest section.

Quiet office to normal conversation
To the human ear, noise in southern West Side sounds about 314% louder than in northwestern West Side, a 20.5 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 83 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 quiet office.

Soft rainfall
Calculated from the model's calibrated attenuation formula. About 12% of West Side sits under tree canopy (about average for neighborhoods) and roughly 67% 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 West Side. 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
Westchester County (HPN) sits west of West Side. 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 West Side, 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 West Side
The bar chart below shows the share of West Side residents in each noise band. About 28% of residents live below the EPA's 55 dBA threshold, and roughly 37% live in blocks above 60 dBA. Long-term exposure in that range is linked to elevated stress hormones and cardiovascular risk.
How West Side Compares
West Side sits the highest among the peer group. Below: how West Side's average outdoor noise and share of residents above the EPA threshold compare with Glenbrook, Turn of River, Cove-East Side, and North Stamford.
Average noise level (dBA)
West Side's 58.2 dBA pop-weighted average is the highest among the peer group. Connecticut as a whole averages 51.3 dBA and the U.S. averages 52.0 dBA. Both are lower than West Side because most of either area is rural land away from major roads.
Share of residents above 55 dBA
About 64.4% of West Side 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, 69.9% of West Side's footprint sits above 55 dBA, against a Connecticut average of 27.3% and a national average of 28.1%.
What This Means if You're Moving to West Side
- 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 West Side 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. Westchester County's approach paths concentrate aviation noise to the west. Neighborhoods to the east of downtown show no measurable contribution from the airport.
