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 4,743 North Coconut Grove residents, or 42.9%, live above that level. By land area, 48.3% of North Coconut Grove is above 55 dBA.
Average noise levels for North Coconut Grove residents, grouped by direction from the center of North Coconut Grove. Northern North Coconut Grove carries the highest population-weighted average; Southern North Coconut Grove carries the lowest. Just 1% of residents in Southern North Coconut Grove live in blocks above the EPA's 55 dBA threshold, a fifth of the share in Northern North Coconut Grove.

QuietLoud
Northern North Coconut Grove sounds about 128% louder than Southern North Coconut Grove to the human ear, a 11.9 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 South Dixie Hway do you need to be?
South Dixie Hway 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.

Soft rainfall
Calculated from the model's calibrated attenuation formula. About 13% of North Coconut Grove sits under tree canopy (about average for neighborhoods) and roughly 44% 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.

Rail Noise
Active freight rail runs through parts of North Coconut Grove. For most blocks the rail-only contribution is small. Combined road-plus-rail noise rarely exceeds road noise on its own. The exceptions are the handful of blocks within roughly a quarter mile of the right-of-way during pass-through hours.
Use the Rail toggle on the map above to isolate rail's contribution from road and aviation.
Airport Noise
Miami International (MIA) sits northwest of North Coconut Grove. 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 45 dBA on the map's Overall layer. Blocks on the opposite side of North Coconut Grove, particularly to the southeast, show no measurable aviation contribution. Use the Aviation toggle on the map above to isolate the airport's footprint.
How Noise Is Distributed Across North Coconut Grove
The bar chart below shows the share of North Coconut Grove residents in each noise band. About 58% 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 North Coconut Grove Compares
North Coconut Grove sits the lowest among the peer group. Below: how North Coconut Grove's average outdoor noise and share of residents above the EPA threshold compare with Upper Eastside, Riviera, Overtown, and North Shores.
Average noise level (dBA)
North Coconut Grove's 52.7 dBA pop-weighted average is the lowest among the peer group. Florida as a whole averages 51.6 dBA and the U.S. averages 52.0 dBA. Both are lower than North Coconut Grove because most of either area is rural land away from major roads.
Share of residents above 55 dBA
About 42.9% of North Coconut Grove 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, 48.3% of North Coconut Grove'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 North Coconut Grove
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 South Dixie Hway 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 13% of North Coconut Grove is under tree cover (about average for neighborhoods), 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. Miami International's approach paths concentrate aviation noise to the northwest. Neighborhoods to the southeast 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.
