This map shows modeled outdoor noise across 06013 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 502 06013 residents, or 5.5%, live above that level. By land area, 9.5% of 06013 is above 55 dBA.

Noise by Part of 06013
Average noise levels for 06013 residents, grouped by direction from the center of 06013. Northern 06013 carries the highest population-weighted average; Central 06013 carries the lowest. Just 0% of residents in Central 06013 live in blocks above the EPA's 55 dBA threshold, a fifth of the share in Northern 06013.
Central 06013
0% of people above 55 dBA
Eastern 06013
9% of people above 55 dBA
Northern 06013
7% of people above 55 dBA
Southern 06013
3% of people above 55 dBA
Western 06013
2% of people above 55 dBA
Northern 06013 sounds about 286% louder than Central 06013 to the human ear, a 19.5 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.
Loudest Road Corridors
The model evaluates every road in 06013 using federal traffic counts, posted speeds, heavy-truck ratios, and pavement type. The source level shown is the modeled noise at the road centerline, where it is loudest. Noise drops with distance, faster in vegetated areas and slower over open pavement.
How far back from Punch Brook Rd do you need to be?
Punch Brook Rd produces an estimated 58 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 72% of 06013 sits under tree canopy (much heavier than most zip codes) and roughly 4% 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
Bradley International (BDL) sits northeast of 06013. 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 65 dBA on the map's Overall layer. Blocks on the opposite side of 06013, particularly to the southwest, show no measurable aviation contribution. Use the Aviation toggle on the map above to isolate the airport's footprint.
How Noise Is Distributed Across 06013
The bar chart below shows the share of 06013 residents in each noise band. About 99% of residents live below the EPA's 55 dBA threshold, and roughly 0% live in blocks above 60 dBA. Long-term exposure in that range is linked to elevated stress hormones and cardiovascular risk.
How 06013 Compares
06013 sits the lowest among the peer group. Below: how 06013's average outdoor noise and share of residents above the EPA threshold compare with 06019, 06786, 06085, and 06710.
Average noise level (dBA)
06013's 45.8 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 06013 because most of either area is rural land away from major roads.
Share of residents above 55 dBA
About 5.5% of 06013 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, 9.5% of 06013'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 06013
- 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 Punch Brook 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 72% of 06013 is under tree cover (much heavier than most zip codes), and the dominant land cover is deciduous forest. 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. Bradley International's approach paths concentrate aviation noise to the northeast. Neighborhoods to the southwest 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.
