Noise Levels in South Valley, Syracuse, NY | Find Quiet Neighborhoods With Our Sound Map

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 1,159 South Valley residents, or 23.1%, live above that level. By land area, 34.6% of South Valley is above 55 dBA.

Noise by Part of South Valley

Average noise levels for South Valley residents, grouped by direction from the center of South Valley. The highest population-weighted average is in southeastern South Valley; the lowest is in western South Valley, where just 14% of residents live in blocks above the EPA's 55 dBA threshold, about half the share in the loudest section.

To the human ear, noise in southeastern South Valley sounds about 111% louder than in western South Valley, a 10.8 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.

Airport Noise

Syracuse Hancock International (SYR) sits north of South Valley. 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 South Valley, particularly to the south, show no measurable aviation contribution. Use the Aviation toggle on the map above to isolate the airport's footprint.

How Noise Is Distributed Across South Valley

The bar chart below shows the share of South Valley residents in each noise band. About 78% of residents live below the EPA's 55 dBA threshold, and roughly 8% live in blocks above 60 dBA. Long-term exposure in that range is linked to elevated stress hormones and cardiovascular risk.

How South Valley Compares

South Valley sits the lowest among the peer group. Below: how South Valley's average outdoor noise and share of residents above the EPA threshold compare with Strathmore, Southwest, Brighton, and Outer Comstock.

Average noise level (dBA)

South Valley's 52.3 dBA pop-weighted average is the lowest among the peer group. New York as a whole averages 55.4 dBA and the U.S. averages 52.0 dBA. Both are lower than South Valley because most of either area is rural land away from major roads.

Share of residents above 55 dBA

About 23.1% of South Valley residents live in blocks where outdoor levels exceed the EPA's 55 dBA threshold. That's fewer than any of its peer group. Measured by land area instead, 34.6% of South Valley's footprint sits above 55 dBA, against a New York average of 30.9% and a national average of 28.1%.

What This Means if You're Moving to South Valley

• 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 I-81 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 42% of South Valley is under tree cover (much heavier than most neighborhoods), and the dominant land cover is low-density developed open space. 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. Syracuse Hancock International's approach paths concentrate aviation noise to the north. Neighborhoods to the south of downtown show no measurable contribution from the airport.
