This map shows modeled outdoor noise across 00911 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 5,251 00911 residents, or 86.7%, live above that level. By land area, 82.3% of 00911 is above 55 dBA.
Average noise levels for 00911 residents, grouped by direction from the center of 00911. Western 00911 carries the highest population-weighted average; Central 00911 carries the lowest. Just 86% of residents in Central 00911 live in blocks above the EPA's 55 dBA threshold, roughly the same as the share in Western 00911.

Western 00911 sounds about 80% louder than Central 00911 to the human ear, a 8.5 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 Pr-26 Wb Front do you need to be?
Pr-26 Wb Front produces an estimated 60 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 00911 sits under tree canopy (about average for zip codes) 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 00911. 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 00911, 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 00911
The bar chart below shows the share of 00911 residents in each noise band. About 6% of residents live below the EPA's 55 dBA threshold, and roughly 59% live in blocks above 60 dBA. Long-term exposure in that range is linked to elevated stress hormones and cardiovascular risk.
How 00911 Compares
00911 sits at the quieter end of the spectrum. Below: how 00911's average outdoor noise and share of residents above the EPA threshold compare with 00913, 00909, 00968, and 00901.
Average noise level (dBA)
00911's 62.0 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 00911 because most of either area is rural land away from major roads.
Share of residents above 55 dBA
About 86.7% of 00911 residents live in blocks where outdoor levels exceed the EPA's 55 dBA threshold. That's more than any of its peer group. Measured by land area instead, 82.3% of 00911'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 00911
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-26 Wb Front 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 00911 is under tree cover (about average for zip codes), 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.
