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 6,348 06905 residents, or 31.7%, live above that level. By land area, 37.9% of 06905 is above 55 dBA.

Noise by Part of 06905
Average noise levels for 06905 residents, grouped by direction from the center of 06905. The highest population-weighted average is in western 06905; the lowest is in northeastern 06905, where just 19% of residents live in blocks above the EPA's 55 dBA threshold, about half the share in the loudest section.

Quiet office to normal conversation
To the human ear, noise in western 06905 sounds about 55% louder than in northeastern 06905, a 6.3 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 Newfield Av do you need to be?
Newfield Av produces an estimated 59 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 46% of 06905 sits under tree canopy (heavier than most zip codes) and roughly 28% 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
Westchester County (HPN) sits west of 06905. 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 06905, 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 06905
The bar chart below shows the share of 06905 residents in each noise band. About 58% of residents live below the EPA's 55 dBA threshold, and roughly 9% live in blocks above 60 dBA. Long-term exposure in that range is linked to elevated stress hormones and cardiovascular risk.
How 06905 Compares
06905 sits at the quieter end of the spectrum. Below: how 06905's average outdoor noise and share of residents above the EPA threshold compare with 06820, 06840, 06850, and 06830.
Average noise level (dBA)
06905's 54.2 dBA pop-weighted average is at the quieter end of the spectrum. Connecticut as a whole averages 51.3 dBA and the U.S. averages 52.0 dBA. Both are lower than 06905 because most of either area is rural land away from major roads.
Share of residents above 55 dBA
About 31.7% of 06905 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, 37.9% of 06905's footprint sits above 55 dBA, against a Connecticut average of 27.3% and a national average of 28.1%.
What This Means if You're Moving to 06905
- 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 Newfield Av 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 46% of 06905 is under tree cover (heavier than most zip codes), 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. Westchester County's approach paths concentrate aviation noise to the west. Neighborhoods to the east of downtown show no measurable contribution from the airport.
