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 1,577 Seccombe Lane residents, or 37.6%, live above that level. By land area, 32.9% of Seccombe Lane is above 55 dBA.
Average noise levels for Seccombe Lane residents, grouped by direction from the center of Seccombe Lane. Southern Seccombe Lane carries the highest population-weighted average; Northern Seccombe Lane carries the lowest. Just 27% of residents in Northern Seccombe Lane live in blocks above the EPA's 55 dBA threshold, three-quarters of the share in Southern Seccombe Lane.

QuietLoud
Southern Seccombe Lane sounds about 28% louder than Northern Seccombe Lane to the human ear, a 3.6 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 3% of Seccombe Lane sits under tree canopy (much lighter than most neighborhoods) and roughly 50% 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
Ontario International (ONT) sits west of Seccombe Lane. 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 Seccombe Lane, particularly to the east, show no measurable aviation contribution. Use the Aviation toggle on the map above to isolate the airport's footprint.
How Noise Is Distributed Across Seccombe Lane
The bar chart below shows the share of Seccombe Lane residents in each noise band. About 54% 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 Seccombe Lane Compares
Seccombe Lane sits the lowest among the peer group. Below: how Seccombe Lane's average outdoor noise and share of residents above the EPA threshold compare with Feldheym, NE-Sterling, Alessandro, and Wildwood Park.
Average noise level (dBA)
Seccombe Lane's 54.1 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 Seccombe Lane because most of either area is rural land away from major roads.
Share of residents above 55 dBA
About 37.6% of Seccombe Lane 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, 32.9% of Seccombe Lane'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 Seccombe Lane
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 3% of Seccombe Lane is under tree cover (much lighter 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. Ontario International's approach paths concentrate aviation noise to the west. Neighborhoods to the east 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.
