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 197 Tariffville residents, or 12.6%, live above that level. By land area, 15.6% of Tariffville is above 55 dBA.

Noise by Part of Tariffville
Average noise levels for Tariffville residents, grouped by direction from the center of Tariffville. Central Tariffville carries the highest population-weighted average; Eastern Tariffville carries the lowest. Just 3% of residents in Eastern Tariffville live in blocks above the EPA's 55 dBA threshold, a fifth of the share in Central Tariffville.

Central Tariffville sounds about 19% louder than Eastern Tariffville to the human ear, a 2.5 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.
How far back from do you need to be?
produces an estimated 65 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 41% of Tariffville sits under tree canopy (heavier than most cities) and roughly 16% 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 Tariffville. 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 45 dBA on the map's Overall layer. Blocks on the opposite side of Tariffville, 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 Tariffville
The bar chart below shows the share of Tariffville residents in each noise band. About 94% 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 Tariffville Compares
Tariffville sits the highest among the peer group. Below: how Tariffville's average outdoor noise and share of residents above the EPA threshold compare with West Granby, Canton Center, East Hartland, and Pine Meadow.
Average noise level (dBA)
Tariffville's 48.9 dBA pop-weighted average is the highest among the peer group. Connecticut as a whole averages 51.3 dBA and the U.S. averages 52.0 dBA. Both are lower than Tariffville because most of either area is rural land away from major roads.
Share of residents above 55 dBA
About 12.6% of Tariffville 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, 15.6% of Tariffville'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 Tariffville
- 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 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 41% of Tariffville is under tree cover (heavier than most cities), 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.
- 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.
