This map shows modeled outdoor noise across Green Island 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 1,413 Green Island residents, or 77.0%, live above that level. By land area, 64.7% of Green Island is above 55 dBA.
Average noise levels for Green Island residents, grouped by direction from the center of Green Island. Central Green Island carries the highest population-weighted average; Northern Green Island carries the lowest. Just 39% of residents in Northern Green Island live in blocks above the EPA's 55 dBA threshold, about half the share in Central Green Island.

QuietLoud
Central Green Island sounds about 52% louder than Northern Green Island to the human ear, a 6.0 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 State Rte 7 do you need to be?
State Rte 7 produces an estimated 77 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 13% of Green Island sits under tree canopy (lighter than most cities) and roughly 71% 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
Albany International (ALB) sits west of Green Island. The U.S. Department of Transportation models aviation noise around this airport from federal traffic data, 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 55 dBA on the map's Overall layer. Blocks on the opposite side of Green Island, 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 Green Island
The bar chart below shows the share of Green Island residents in each noise band. About 20% of residents live below the EPA's 55 dBA threshold, and roughly 45% live in blocks above 60 dBA. Long-term exposure in that range is linked to elevated stress hormones and cardiovascular risk.
How Green Island Compares
Green Island sits the highest among the peer group. Below: how Green Island's average outdoor noise and share of residents above the EPA threshold compare with Melrose, Poestenkill, Valley Falls, and Johnsonville.
Average noise level (dBA)
Green Island's 59.3 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 Green Island because most of either area is rural land away from major roads.
Share of residents above 55 dBA
About 77.0% of Green Island 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, 64.7% of Green Island'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 Green Island
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 State Rte 7 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 13% of Green Island is under tree cover (lighter than most cities), 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. Albany 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.
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.
