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 5,086 Brooklawn-St. Vincent residents, or 39.8%, live above that level. By land area, 41.5% of Brooklawn-St. Vincent is above 55 dBA.
Average noise levels for Brooklawn-St. Vincent residents, grouped by direction from the center of Brooklawn-St. Vincent. Eastern Brooklawn-St. Vincent carries the highest population-weighted average; Central Brooklawn-St. Vincent carries the lowest. Just 31% of residents in Central Brooklawn-St. Vincent live in blocks above the EPA's 55 dBA threshold, about two-thirds of the share in Eastern Brooklawn-St. Vincent.

QuietLoud
Eastern Brooklawn-St. Vincent sounds about 45% louder than Central Brooklawn-St. Vincent to the human ear, a 5.4 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 Park Av do you need to be?
Park Av produces an estimated 57 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 17% of Brooklawn-St. Vincent sits under tree canopy (about average for neighborhoods) and roughly 58% 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.

How Noise Is Distributed Across Brooklawn-St. Vincent
The bar chart below shows the share of Brooklawn-St. Vincent residents in each noise band. About 54% of residents live below the EPA's 55 dBA threshold, and roughly 7% live in blocks above 60 dBA. Long-term exposure in that range is linked to elevated stress hormones and cardiovascular risk.
How Brooklawn-St. Vincent Compares
Brooklawn-St. Vincent sits at the quieter end of the spectrum. Below: how Brooklawn-St. Vincent's average outdoor noise and share of residents above the EPA threshold compare with North End, Bassickville Historic District, East Side-Bridgeport, and Devon-Walnut Beach.
Average noise level (dBA)
Brooklawn-St. Vincent's 55.0 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 Brooklawn-St. Vincent because most of either area is rural land away from major roads.
Share of residents above 55 dBA
About 39.8% of Brooklawn-St. Vincent 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, 41.5% of Brooklawn-St. Vincent'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 Brooklawn-St. Vincent
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 Park 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 17% of Brooklawn-St. Vincent is under tree cover (about average for neighborhoods), 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.
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.
