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 457 33449 residents, or 5.3%, live above that level. By land area, 9.7% of 33449 is above 55 dBA.

Noise by Part of 33449
Average noise levels for 33449 residents, grouped by direction from the center of 33449. The highest population-weighted average is in northern 33449; the lowest is in southern 33449, where just 2% of residents live in blocks above the EPA's 55 dBA threshold, a third of the share in the loudest section.

Quiet suburban street at night
To the human ear, noise in northern 33449 sounds about 45% louder than in southern 33449, a 5.4 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 SR-7 /us-441 do you need to be?
SR-7 /us-441 produces an estimated 70 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.

Soft rainfall
Calculated from the model's calibrated attenuation formula. About 11% of 33449 sits under tree canopy (lighter than most zip codes) and roughly 43% 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
Palm Beach International (PBI) sits northeast of 33449. 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 33449, 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 33449
The bar chart below shows the share of 33449 residents in each noise band. About 100% of residents live below the EPA's 55 dBA threshold, and roughly 0% live in blocks above 60 dBA. Long-term exposure in that range is linked to elevated stress hormones and cardiovascular risk.
How 33449 Compares
33449 sits at the quieter end of the spectrum. Below: how 33449's average outdoor noise and share of residents above the EPA threshold compare with 33473, 33480, 33413, and 33472.
Average noise level (dBA)
33449's 45.0 dBA pop-weighted average is at the quieter end of the spectrum. Florida as a whole averages 51.6 dBA and the U.S. averages 52.0 dBA. Both are lower than 33449 because most of either area is rural land away from major roads.
Share of residents above 55 dBA
About 5.3% of 33449 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, 9.7% of 33449's footprint sits above 55 dBA, against a Florida average of 31.8% and a national average of 28.1%.
What This Means if You're Moving to 33449
- 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 SR-7 /us-441 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 11% of 33449 is under tree cover (lighter than most zip codes), and the dominant land cover is medium-intensity developed land. 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. Palm Beach International's approach paths concentrate aviation noise to the northeast. Neighborhoods to the southwest of downtown show no measurable contribution from the airport.
