This map shows modeled outdoor noise across 34711 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 9,142 34711 residents, or 15.4%, live above that level. By land area, 21.6% of 34711 is above 55 dBA.

Noise by Part of 34711
Average noise levels for 34711 residents, grouped by direction from the center of 34711. The highest population-weighted average is in northern 34711; the lowest is in western 34711, where just 10% of residents live in blocks above the EPA's 55 dBA threshold, about half the share in the loudest section.

To the human ear, noise in northern 34711 sounds about 71% louder than in western 34711, a 7.7 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 US-27 do you need to be?
US-27 produces an estimated 69 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 14% of 34711 sits under tree canopy (lighter than most zip codes) and roughly 36% 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
Orlando International (MCO) sits east of 34711. The U.S. Department of Transportation measures aviation noise around this airport directly, 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 75 dBA on the map's Overall layer. Blocks on the opposite side of 34711, 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 34711
The bar chart below shows the share of 34711 residents in each noise band. About 88% of residents live below the EPA's 55 dBA threshold, and roughly 2% live in blocks above 60 dBA. Long-term exposure in that range is linked to elevated stress hormones and cardiovascular risk.
How 34711 Compares
34711 sits at the quieter end of the spectrum. Below: how 34711's average outdoor noise and share of residents above the EPA threshold compare with 34787, 32703, 32839, and 34786.
Average noise level (dBA)
34711's 50.1 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 34711 because most of either area is rural land away from major roads.
Share of residents above 55 dBA
About 15.4% of 34711 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, 21.6% of 34711'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 34711
- 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 US-27 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 14% of 34711 is under tree cover (lighter than most zip codes), and the dominant land cover is low-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. Orlando International's approach paths concentrate aviation noise to the east. Neighborhoods to the west of downtown show no measurable contribution from the airport.
