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 3,107 Barrio Amelia residents, or 84.8%, live above that level. By land area, 73.5% of Barrio Amelia is above 55 dBA.
Average noise levels for Barrio Amelia residents, grouped by direction from the center of Barrio Amelia. Northern Barrio Amelia carries the highest population-weighted average; Eastern Barrio Amelia carries the lowest. Just 24% of residents in Eastern Barrio Amelia live in blocks above the EPA's 55 dBA threshold, a third of the share in Northern Barrio Amelia.

QuietLoud
Northern Barrio Amelia sounds about 36% louder than Eastern Barrio Amelia to the human ear, a 4.4 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 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 Barrio Amelia sits under tree canopy (about average for neighborhoods) 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
Luis Munoz Marin International (SJU) sits east of Barrio Amelia. 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 Barrio Amelia, particularly to the west, show no measurable aviation contribution. Use the Aviation toggle on the map above to isolate the airport's footprint.
How Noise Is Distributed Across Barrio Amelia
The bar chart below shows the share of Barrio Amelia residents in each noise band. About 10% of residents live below the EPA's 55 dBA threshold, and roughly 24% live in blocks above 60 dBA. Long-term exposure in that range is linked to elevated stress hormones and cardiovascular risk.
How Barrio Amelia Compares
Barrio Amelia sits at the quieter end of the spectrum. Below: how Barrio Amelia's average outdoor noise and share of residents above the EPA threshold compare with Reparto Metropolitano, Extencion Roosevelt, Urbanizacion Atlantic View, and Urbanizacion Las Vegas.
Average noise level (dBA)
Barrio Amelia's 58.6 dBA pop-weighted average is at the quieter end of the spectrum. Puerto Rico as a whole averages 52.9 dBA and the U.S. averages 52.0 dBA. Both are lower than Barrio Amelia because most of either area is rural land away from major roads.
Share of residents above 55 dBA
About 84.8% of Barrio Amelia 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, 73.5% of Barrio Amelia's footprint sits above 55 dBA, against a Puerto Rico average of 36.1% and a national average of 28.1%.
What This Means if You're Moving to Barrio Amelia
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 Barrio Amelia is under tree cover (about average for neighborhoods), 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. Luis Munoz Marin International's approach paths concentrate aviation noise to the east. Neighborhoods to the west 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.
