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 6,033 Downtown Brooklyn residents, or 90.5%, live above that level. By land area, 94.0% of Downtown Brooklyn is above 55 dBA.
Average noise levels for Downtown Brooklyn residents, grouped by direction from the center of Downtown Brooklyn. Western Downtown Brooklyn carries the highest population-weighted average; Central Downtown Brooklyn carries the lowest. Just 88% of residents in Central Downtown Brooklyn live in blocks above the EPA's 55 dBA threshold, roughly the same as the share in Western Downtown Brooklyn.

QuietLoud
Western Downtown Brooklyn sounds about 46% louder than Central Downtown Brooklyn to the human ear, a 5.5 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 79 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 4% of Downtown Brooklyn sits under tree canopy (much lighter than most neighborhoods) and roughly 80% 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.

Airport Noise
Laguardia (LGA) sits northeast of Downtown Brooklyn. 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 Downtown Brooklyn, particularly to the southwest, show no measurable aviation contribution. Use the Aviation toggle on the map above to isolate the airport's footprint.
How Noise Is Distributed Across Downtown Brooklyn
The bar chart below shows the share of Downtown Brooklyn residents in each noise band. About 0% of residents live below the EPA's 55 dBA threshold, and roughly 46% live in blocks above 60 dBA. Long-term exposure in that range is linked to elevated stress hormones and cardiovascular risk.
How Downtown Brooklyn Compares
Downtown Brooklyn sits at the quieter end of the spectrum. Below: how Downtown Brooklyn's average outdoor noise and share of residents above the EPA threshold compare with Cobble Hill, Columbia Street Waterfront District, Prospect Lefferts Gardens, and Chinatown.
Average noise level (dBA)
Downtown Brooklyn's 61.7 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 Downtown Brooklyn because most of either area is rural land away from major roads.
Share of residents above 55 dBA
About 90.5% of Downtown Brooklyn 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, 94.0% of Downtown Brooklyn'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 Downtown Brooklyn
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 4% of Downtown Brooklyn 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 northeast. Neighborhoods to the southwest 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.
