Western Urbanizacion Las Lomas sounds about 82% louder than Central Urbanizacion Las Lomas to the human ear, a 8.6 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 79 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 Urbanizacion Las Lomas 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 Las Lomas. 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 Las Lomas, 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 Las Lomas
The bar chart below shows the share of Urbanizacion Las Lomas residents in each noise band. About 46% of residents live below the EPA's 55 dBA threshold, and roughly 9% live in blocks above 60 dBA. Long-term exposure in that range is linked to elevated stress hormones and cardiovascular risk.
How Urbanizacion Las Lomas Compares
Urbanizacion Las Lomas sits the lowest among the peer group. Below: how Urbanizacion Las Lomas's average outdoor noise and share of residents above the EPA threshold compare with Urbanizacion Santiago Iglesias, Extencion Roosevelt, Urbanizacion San Agustin, and Reparto Metropolitano.
Average noise level (dBA)
Urbanizacion Las Lomas's 54.2 dBA pop-weighted average is the lowest among the peer group. Puerto Rico as a whole averages 52.9 dBA and the U.S. averages 52.0 dBA. Both are lower than Urbanizacion Las Lomas because most of either area is rural land away from major roads.
Share of residents above 55 dBA
About 42.0% of Urbanizacion Las Lomas 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, 52.0% of Urbanizacion Las Lomas'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 Las Lomas
- 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 Urbanizacion Las Lomas 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.
