This map shows modeled outdoor noise across Suburban Acres 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 1,948 Suburban Acres residents, or 73.4%, live above that level. By land area, 69.8% of Suburban Acres is above 55 dBA.

Noise by Part of Suburban Acres
Average noise levels for Suburban Acres residents, grouped by direction from the center of Suburban Acres. The highest population-weighted average is in western Suburban Acres; the lowest is in central Suburban Acres, where just 63% of residents live in blocks above the EPA's 55 dBA threshold, roughly the same as the share in the loudest section.

Central Suburban Acres

Normal conversation an arm’s length away
To the human ear, noise in western Suburban Acres sounds about 17% louder than in central Suburban Acres, a 2.3 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 68 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 29% of Suburban Acres sits under tree canopy (heavier than most neighborhoods) and roughly 46% 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.

Rail Noise
Active freight rail runs through parts of Suburban Acres. 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.
Airport Noise
Norfolk International (ORF) sits east of Suburban Acres. 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 Suburban Acres, 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 Suburban Acres
The bar chart below shows the share of Suburban Acres residents in each noise band. About 20% of residents live below the EPA's 55 dBA threshold, and roughly 18% live in blocks above 60 dBA. Long-term exposure in that range is linked to elevated stress hormones and cardiovascular risk.
How Suburban Acres Compares
Suburban Acres sits the lowest among the peer group. Below: how Suburban Acres's average outdoor noise and share of residents above the EPA threshold compare with norview-norfolk-va, chesapeake-gardens-mamie-homes-norfolk-va, poplar-hills-norfolk-va, and Park Place.
Average noise level (dBA)
Suburban Acres's 57.5 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 Suburban Acres because most of either area is rural land away from major roads.
Share of residents above 55 dBA
About 73.4% of Suburban Acres 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, 69.8% of Suburban Acres'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 Suburban Acres
- 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 29% of Suburban Acres is under tree cover (heavier than most 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.
- 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.
