This map shows modeled outdoor noise across Financial District 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 18,136 Financial District residents, or 90.3%, live above that level. By land area, 91.0% of Financial District is above 55 dBA.

Noise by Part of Financial District
Average noise levels for Financial District residents, grouped by direction from the center of Financial District. The highest population-weighted average is in eastern Financial District; the lowest is in central Financial District, where just 94% of residents live in blocks above the EPA's 55 dBA threshold, roughly the same as the share in the loudest section.
Eastern Financial District
100% of people above 55 dBA
Western Financial District
100% of people above 55 dBA
Southwestern Financial District
97% of people above 55 dBA
Northwestern Financial District
93% of people above 55 dBA
Central Financial District
94% of people above 55 dBA
To the human ear, noise in eastern Financial District sounds about 45% louder than in central Financial District, a 5.4 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
Newark Liberty International (EWR) sits west of Financial District. 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 Financial District, 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 Financial District
The bar chart below shows the share of Financial District residents in each noise band. About 0% of residents live below the EPA's 55 dBA threshold, and roughly 86% live in blocks above 60 dBA. Long-term exposure in that range is linked to elevated stress hormones and cardiovascular risk.
How Financial District Compares
Financial District sits at the quieter end of the spectrum. Below: how Financial District's average outdoor noise and share of residents above the EPA threshold compare with Boerum Hill, Murray Hill, Theater District, and Greenwood.
Average noise level (dBA)
Financial District's 62.6 dBA pop-weighted average is at the quieter end of the spectrum. New York as a whole averages 55.4 dBA and the U.S. averages 52.0 dBA. Both are lower than Financial District because most of either area is rural land away from major roads.
Share of residents above 55 dBA
About 90.3% of Financial District 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, 91.0% of Financial District'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 Financial District
- 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 0% of Financial District 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. Newark Liberty International's approach paths concentrate aviation noise to the west. Neighborhoods to the east 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.
Federal datasets used:
FHWA Highway Performance Monitoring System: road geometry, traffic counts, lane configuration
U.S. DoT Bureau of Transportation Statistics National Transportation Noise Map: aviation and rail noise, road calibration ground truth
USGS / MRLC National Land Cover Database: land cover and impervious surface coverage
USDA Forest Service Tree Canopy Cover: vegetation density for sound propagation
U.S. Census Bureau TIGER/Line: block-level geography and population
U.S. EPA Levels Document: 55 dBA outdoor reference level
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.
