This map shows modeled outdoor noise across Oyster Bay Cove 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 145 Oyster Bay Cove residents, or 8.0%, live above that level. By land area, 14.9% of Oyster Bay Cove is above 55 dBA.

Airport Noise
Laguardia (LGA) sits west of Oyster Bay Cove. 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 Oyster Bay Cove, 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 Oyster Bay Cove
The bar chart below shows the share of Oyster Bay Cove residents in each noise band. About 94% of residents live below the EPA's 55 dBA threshold, and roughly 1% live in blocks above 60 dBA. Long-term exposure in that range is linked to elevated stress hormones and cardiovascular risk.
How Oyster Bay Cove Compares
Oyster Bay Cove sits the lowest among the peer group. Below: how Oyster Bay Cove's average outdoor noise and share of residents above the EPA threshold compare with Laurel Hollow, Upper Brookville, Lattingtown, and Old Brookville.
Average noise level (dBA)
Oyster Bay Cove's 45.7 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 Oyster Bay Cove because most of either area is rural land away from major roads.
Share of residents above 55 dBA
About 8.0% of Oyster Bay Cove 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, 14.9% of Oyster Bay Cove'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 Oyster Bay Cove
- 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 Berry Hill Rd 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 62% of Oyster Bay Cove is under tree cover (much heavier than most cities), 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. Laguardia'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.
