This map shows modeled outdoor noise across Rossmoyne 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 5,028 Rossmoyne residents, or 63.0%, live above that level. By land area, 51.4% of Rossmoyne is above 55 dBA.

Noise by Part of Rossmoyne
Average noise levels for Rossmoyne residents, grouped by direction from the center of Rossmoyne. The highest population-weighted average is in southern Rossmoyne; the lowest is in northwestern Rossmoyne, where just 34% of residents live in blocks above the EPA's 55 dBA threshold, a third of the share in the loudest section.

Quiet office to normal conversation
To the human ear, noise in southern Rossmoyne sounds about 406% louder than in northwestern Rossmoyne, a 23.4 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 State Rte 134 do you need to be?
State Rte 134 produces an estimated 80 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 3% of Rossmoyne sits under tree canopy (much lighter than most neighborhoods) and roughly 65% 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
Bob Hope (BUR) sits northwest of Rossmoyne. 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 Rossmoyne, particularly to the southeast, show no measurable aviation contribution. Use the Aviation toggle on the map above to isolate the airport's footprint.
How Noise Is Distributed Across Rossmoyne
The bar chart below shows the share of Rossmoyne residents in each noise band. About 37% of residents live below the EPA's 55 dBA threshold, and roughly 40% live in blocks above 60 dBA. Long-term exposure in that range is linked to elevated stress hormones and cardiovascular risk.
How Rossmoyne Compares
Rossmoyne sits the highest among the peer group. Below: how Rossmoyne's average outdoor noise and share of residents above the EPA threshold compare with Glenwood, Verdugo Viejo, Pacific Edison, and Montrose Verdugo City.
Average noise level (dBA)
Rossmoyne's 59.6 dBA pop-weighted average is the highest among the peer group. California as a whole averages 54.0 dBA and the U.S. averages 52.0 dBA. Both are lower than Rossmoyne because most of either area is rural land away from major roads.
Share of residents above 55 dBA
About 63.0% of Rossmoyne 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, 51.4% of Rossmoyne'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 Rossmoyne
- 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 State Rte 134 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 Rossmoyne is under tree cover (much lighter 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. Bob Hope's approach paths concentrate aviation noise to the northwest. Neighborhoods to the southeast of downtown show no measurable contribution from the airport.
