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 2,418 Larchmont-Edgewater residents, or 46.0%, live above that level. By land area, 54.5% of Larchmont-Edgewater is above 55 dBA.

Noise by Part of Larchmont-Edgewater
Average noise levels for Larchmont-Edgewater residents, grouped by direction from the center of Larchmont-Edgewater. The highest population-weighted average is in southeastern Larchmont-Edgewater; the lowest is in northeastern Larchmont-Edgewater, where just 25% of residents live in blocks above the EPA's 55 dBA threshold, about two-thirds of the share in the loudest section.

Quiet office to normal conversation
To the human ear, noise in southeastern Larchmont-Edgewater sounds about 43% louder than in northeastern Larchmont-Edgewater, a 5.2 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 70 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 26% of Larchmont-Edgewater sits under tree canopy (heavier than most neighborhoods) and roughly 41% 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
Norfolk International (ORF) sits east of Larchmont-Edgewater. 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 Larchmont-Edgewater, particularly to the west, show no measurable aviation contribution. Use the Aviation toggle on the map above to isolate the airport's footprint.
How Noise Is Distributed Across Larchmont-Edgewater
The bar chart below shows the share of Larchmont-Edgewater residents in each noise band. About 48% of residents live below the EPA's 55 dBA threshold, and roughly 3% live in blocks above 60 dBA. Long-term exposure in that range is linked to elevated stress hormones and cardiovascular risk.
How Larchmont-Edgewater Compares
Larchmont-Edgewater sits the lowest among the peer group. Below: how Larchmont-Edgewater's average outdoor noise and share of residents above the EPA threshold compare with Downtown Norfolk, Colonial Place Riverview, West Ocean View, and Oakdale Farms.
Average noise level (dBA)
Larchmont-Edgewater's 54.4 dBA pop-weighted average is the lowest among the peer group. Virginia as a whole averages 52.8 dBA and the U.S. averages 52.0 dBA. Both are lower than Larchmont-Edgewater because most of either area is rural land away from major roads.
Share of residents above 55 dBA
About 46.0% of Larchmont-Edgewater 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, 54.5% of Larchmont-Edgewater's footprint sits above 55 dBA, against a Virginia average of 30.0% and a national average of 28.1%.
What This Means if You're Moving to Larchmont-Edgewater
- 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 26% of Larchmont-Edgewater 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.
- Airport noise is directional. Norfolk International's approach paths concentrate aviation noise to the east. Neighborhoods to the west of downtown show no measurable contribution from the airport.
