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 4,206 Marina Del Rey residents, or 30.7%, live above that level. By land area, 40.6% of Marina Del Rey is above 55 dBA.
Average noise levels for Marina Del Rey residents, grouped by direction from the center of Marina Del Rey. Eastern Marina Del Rey carries the highest population-weighted average; Central Marina Del Rey carries the lowest. Just 0% of residents in Central Marina Del Rey live in blocks above the EPA's 55 dBA threshold, a fifth of the share in Eastern Marina Del Rey.

QuietLoud
Eastern Marina Del Rey sounds about 1031% louder than Central Marina Del Rey to the human ear, a 35.0 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 81 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 quiet suburban street at night.

Soft rainfall
Calculated from the model's calibrated attenuation formula. About 0% of Marina Del Rey sits under tree canopy (much lighter than most cities) and roughly 79% 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
Los Angeles International (LAX) sits southeast of Marina Del Rey. The U.S. Department of Transportation measures aviation noise around this airport directly, 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 Marina Del Rey, particularly to the northwest, show no measurable aviation contribution. Use the Aviation toggle on the map above to isolate the airport's footprint.
How Noise Is Distributed Across Marina Del Rey
The bar chart below shows the share of Marina Del Rey residents in each noise band. About 62% 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 Marina Del Rey Compares
Marina Del Rey sits the lowest among the peer group. Below: how Marina Del Rey's average outdoor noise and share of residents above the EPA threshold compare with El Segundo, Hermosa Beach, Playa Del Rey, and Lennox.
Average noise level (dBA)
Marina Del Rey's 54.5 dBA pop-weighted average is the lowest among the peer group. California as a whole averages 54.0 dBA and the U.S. averages 52.0 dBA. Both are lower than Marina Del Rey because most of either area is rural land away from major roads.
Share of residents above 55 dBA
About 30.7% of Marina Del Rey 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, 40.6% of Marina Del Rey's footprint sits above 55 dBA, against a California average of 36.0% and a national average of 28.1%.
What This Means if You're Moving to Marina Del Rey
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 0% of Marina Del Rey is under tree cover (much lighter than most cities), and the dominant land cover is high-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. Los Angeles International's approach paths concentrate aviation noise to the southeast. Neighborhoods to the northwest 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.
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.
