Noise by Part of Devon-Walnut Beach

Average noise levels for Devon-Walnut Beach residents, grouped by direction from the center of Devon-Walnut Beach. The highest population-weighted average is in northwestern Devon-Walnut Beach; the lowest is in eastern Devon-Walnut Beach, where just 12% of residents live in blocks above the EPA's 55 dBA threshold, a fifth of the share in the loudest section.

To the human ear, noise in northwestern Devon-Walnut Beach sounds about 214% louder than in eastern Devon-Walnut Beach, a 16.5 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.

Rail Noise

Active freight rail runs through parts of Devon-Walnut Beach. For most blocks the rail-only contribution is small. Combined road-plus-rail noise rarely exceeds road noise on its own. The exceptions are the handful of blocks within roughly a quarter mile of the right-of-way during pass-through hours.

Use the Rail toggle on the map above to isolate rail's contribution from road and aviation.

How Noise Is Distributed Across Devon-Walnut Beach

The bar chart below shows the share of Devon-Walnut Beach residents in each noise band. About 77% of residents live below the EPA's 55 dBA threshold, and roughly 4% live in blocks above 60 dBA. Long-term exposure in that range is linked to elevated stress hormones and cardiovascular risk.

How Devon-Walnut Beach Compares

Devon-Walnut Beach sits the lowest among the peer group. Below: how Devon-Walnut Beach's average outdoor noise and share of residents above the EPA threshold compare with East Side-Bridgeport, Boston Avenue-Mill Hill, North Bridgeport, and Brooklawn-St. Vincent.

Average noise level (dBA)

Devon-Walnut Beach's 52.2 dBA pop-weighted average is the lowest among the peer group. Connecticut as a whole averages 51.3 dBA and the U.S. averages 52.0 dBA. Both are lower than Devon-Walnut Beach because most of either area is rural land away from major roads.

Share of residents above 55 dBA

About 27.9% of Devon-Walnut Beach residents live in blocks where outdoor levels exceed the EPA's 55 dBA threshold. That's fewer than any of its peer group. Measured by land area instead, 37.5% of Devon-Walnut Beach'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 Devon-Walnut Beach

• 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 Milford Point 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 24% of Devon-Walnut Beach is under tree cover (heavier than most neighborhoods), and the dominant land cover is low-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.
