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 Pr-831 do you need to be?
Pr-831 produces an estimated 61 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 0% of Urbanizacion Santa Juanita 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 northeast of Urbanizacion Santa Juanita. 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 Urbanizacion Santa Juanita, particularly to the southwest, show no measurable aviation contribution. Use the Aviation toggle on the map above to isolate the airport's footprint.
How Noise Is Distributed Across Urbanizacion Santa Juanita
The bar chart below shows the share of Urbanizacion Santa Juanita residents in each noise band. About 71% of residents live below the EPA's 55 dBA threshold, and roughly 4% live in blocks above 60 dBA. Long-term exposure in that range is linked to elevated stress hormones and cardiovascular risk.
How Urbanizacion Santa Juanita Compares
Urbanizacion Santa Juanita sits at the quieter end of the spectrum. Below: how Urbanizacion Santa Juanita's average outdoor noise and share of residents above the EPA threshold compare with Urbanizacion Puerto Nuevo, Lomas Verdes, Urbanizacion Sierra Bayamon, and Jardines de Caparra.
Average noise level (dBA)
Urbanizacion Santa Juanita's 53.7 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 Urbanizacion Santa Juanita because most of either area is rural land away from major roads.
Share of residents above 55 dBA
About 41.1% of Urbanizacion Santa Juanita 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, 48.5% of Urbanizacion Santa Juanita'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 Urbanizacion Santa Juanita
- 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 Pr-831 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 Urbanizacion Santa Juanita 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 northeast. Neighborhoods to the southwest of downtown show no measurable contribution from the airport.
