This map shows modeled outdoor noise across Chelsea 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 63,240 Chelsea residents, or 96.3%, live above that level. By land area, 95.5% of Chelsea is above 55 dBA.
Average noise levels for Chelsea residents, grouped by direction from the center of Chelsea. Northern Chelsea carries the highest population-weighted average; Southern Chelsea carries the lowest. Just 91% of residents in Southern Chelsea live in blocks above the EPA's 55 dBA threshold, roughly the same as the share in Northern Chelsea.

QuietLoud
Northern Chelsea sounds about 26% louder than Southern Chelsea to the human ear, a 3.3 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 74 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 1% of Chelsea sits under tree canopy (much lighter than most neighborhoods) and roughly 82% 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 Chelsea. 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 east of Chelsea. 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 75 dBA on the map's Overall layer. Blocks on the opposite side of Chelsea, particularly to the west, show no measurable aviation contribution. Use the Aviation toggle on the map above to isolate the airport's footprint.
How Noise Is Distributed Across Chelsea
The bar chart below shows the share of Chelsea residents in each noise band. About 0% of residents live below the EPA's 55 dBA threshold, and roughly 80% live in blocks above 60 dBA. Long-term exposure in that range is linked to elevated stress hormones and cardiovascular risk.
How Chelsea Compares
Chelsea sits the highest among the peer group. Below: how Chelsea's average outdoor noise and share of residents above the EPA threshold compare with Lower East Side, Mott Haven, Elmhurst, and East Village.
Average noise level (dBA)
Chelsea's 63.3 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 Chelsea because most of either area is rural land away from major roads.
Share of residents above 55 dBA
About 96.3% of Chelsea 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, 95.5% of Chelsea'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 Chelsea
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 1% of Chelsea is under tree cover (much lighter than most neighborhoods), and the dominant land cover is high-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 east. Neighborhoods to the west 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.
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.
