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 251 Hickam Housing residents, or 6.2%, live above that level. By land area, 22.1% of Hickam Housing is above 55 dBA.
Average noise levels for Hickam Housing residents, grouped by direction from the center of Hickam Housing. Southern Hickam Housing carries the highest population-weighted average; Northern Hickam Housing carries the lowest. Just 4% of residents in Northern Hickam Housing live in blocks above the EPA's 55 dBA threshold, a fifth of the share in Southern Hickam Housing.

QuietLoud
Southern Hickam Housing sounds about 223% louder than Northern Hickam Housing to the human ear, a 16.9 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 82 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 Hickam Housing sits under tree canopy (about average for cities) and roughly 0% 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
Daniel K Inouye International (HNL) sits southeast of Hickam Housing. 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 80 dBA on the map's Overall layer. Blocks on the opposite side of Hickam Housing, 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 Hickam Housing
The bar chart below shows the share of Hickam Housing residents in each noise band. About 96% of residents live below the EPA's 55 dBA threshold, and roughly 3% live in blocks above 60 dBA. Long-term exposure in that range is linked to elevated stress hormones and cardiovascular risk.
How Hickam Housing Compares
Hickam Housing sits the lowest among the peer group. Below: how Hickam Housing's average outdoor noise and share of residents above the EPA threshold compare with Halawa, Pearl Harbor, Waimanalo Beach, and Hauula.
Average noise level (dBA)
Hickam Housing's 47.6 dBA pop-weighted average is the lowest among the peer group. Hawaii as a whole averages 54.8 dBA and the U.S. averages 52.0 dBA. Both are lower than Hickam Housing because most of either area is rural land away from major roads.
Share of residents above 55 dBA
About 6.2% of Hickam Housing 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, 22.1% of Hickam Housing's footprint sits above 55 dBA, against a Hawaii average of 34.4% and a national average of 28.1%.
What This Means if You're Moving to Hickam Housing
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 Hickam Housing is under tree cover (about average for cities), and the dominant land cover is . 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. Daniel K Inouye 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.
