Noise Levels in East Harlem, Manhattan, NY | Find Quiet Neighborhoods With Our Sound Map

Rail Noise

Active freight rail runs through parts of East Harlem. 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

Laguardia (LGA) sits southeast of East Harlem. 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 45 dBA on the map's Overall layer. Blocks on the opposite side of East Harlem, particularly to the northwest, show no measurable aviation contribution. Use the Aviation toggle on the map above to isolate the airport's footprint.

How Noise Is Distributed Across East Harlem

The bar chart below shows the share of East Harlem residents in each noise band. About 0% of residents live below the EPA's 55 dBA threshold, and roughly 88% live in blocks above 60 dBA. Long-term exposure in that range is linked to elevated stress hormones and cardiovascular risk.

How East Harlem Compares

East Harlem sits the highest among the peer group. Below: how East Harlem's average outdoor noise and share of residents above the EPA threshold compare with Carnegie Hill, Long Island City, Yorkville, and Midtown.

Average noise level (dBA)

East Harlem's 64.9 dBA pop-weighted average is the highest 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 East Harlem because most of either area is rural land away from major roads.

Share of residents above 55 dBA

About 100.0% of East Harlem 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, 100.0% of East Harlem'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 East Harlem

• 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 E River Dr 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 4% of East Harlem is under tree cover (much 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. Laguardia's approach paths concentrate aviation noise to the southeast. Neighborhoods to the northwest of downtown show no measurable contribution from the airport.
