This map shows modeled outdoor noise across Hawaiian Gardens 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 4,318 Hawaiian Gardens residents, or 38.8%, live above that level. By land area, 46.7% of Hawaiian Gardens is above 55 dBA.

Noise by Part of Hawaiian Gardens
Average noise levels for Hawaiian Gardens residents, grouped by direction from the center of Hawaiian Gardens. Western Hawaiian Gardens carries the highest population-weighted average; Northern Hawaiian Gardens carries the lowest. Just 16% of residents in Northern Hawaiian Gardens live in blocks above the EPA's 55 dBA threshold, a fifth of the share in Western Hawaiian Gardens.

Normal conversation an arm’s length away
Western Hawaiian Gardens sounds about 99% louder than Northern Hawaiian Gardens to the human ear, a 9.9 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 84 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 office.

Soft rainfall
Calculated from the model's calibrated attenuation formula. About 3% of Hawaiian Gardens sits under tree canopy (much lighter than most cities) and roughly 66% 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
Long Beach (Daugherty Field) (LGB) sits west of Hawaiian Gardens. 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 55 dBA on the map's Overall layer. Blocks on the opposite side of Hawaiian Gardens, 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 Hawaiian Gardens
The bar chart below shows the share of Hawaiian Gardens residents in each noise band. About 58% of residents live below the EPA's 55 dBA threshold, and roughly 12% live in blocks above 60 dBA. Long-term exposure in that range is linked to elevated stress hormones and cardiovascular risk.
How Hawaiian Gardens Compares
Hawaiian Gardens sits the lowest among the peer group. Below: how Hawaiian Gardens's average outdoor noise and share of residents above the EPA threshold compare with Rossmoor, Los Alamitos, Midway City, and Signal Hill.
Average noise level (dBA)
Hawaiian Gardens's 54.0 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 Hawaiian Gardens because most of either area is rural land away from major roads.
Share of residents above 55 dBA
About 38.8% of Hawaiian Gardens 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, 46.7% of Hawaiian Gardens'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 Hawaiian Gardens
- 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 Hawaiian Gardens is under tree cover (much lighter than most cities), 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. Long Beach (Daugherty Field)'s approach paths concentrate aviation noise to the west. Neighborhoods to the east of downtown show no measurable contribution from the airport.
