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 586 Ravine Gardens residents, or 17.6%, live above that level. By land area, 24.3% of Ravine Gardens is above 55 dBA.

Noise by Part of Ravine Gardens
Average noise levels for Ravine Gardens residents, grouped by direction from the center of Ravine Gardens. The highest population-weighted average is in southern Ravine Gardens; the lowest is in western Ravine Gardens, where just 12% of residents live in blocks above the EPA's 55 dBA threshold, about half the share in the loudest section.

Quiet office to normal conversation
To the human ear, noise in southern Ravine Gardens sounds about 41% louder than in western Ravine Gardens, a 5.0 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 Monmouth County 6A Ii do you need to be?
Monmouth County 6A Ii produces an estimated 57 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 34% of Ravine Gardens sits under tree canopy (much heavier than most neighborhoods) and roughly 38% 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
Newark Liberty International (EWR) sits north of Ravine Gardens. 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 Ravine Gardens, particularly to the south, show no measurable aviation contribution. Use the Aviation toggle on the map above to isolate the airport's footprint.
How Noise Is Distributed Across Ravine Gardens
The bar chart below shows the share of Ravine Gardens residents in each noise band. About 84% of residents live below the EPA's 55 dBA threshold, and roughly 3% live in blocks above 60 dBA. Long-term exposure in that range is linked to elevated stress hormones and cardiovascular risk.
How Ravine Gardens Compares
Ravine Gardens sits at the louder end of the spectrum. Below: how Ravine Gardens's average outdoor noise and share of residents above the EPA threshold compare with Southwood, Townelake, La Mer, and Bonhamtown.
Average noise level (dBA)
Ravine Gardens's 48.9 dBA pop-weighted average is at the louder end of the spectrum. New Jersey as a whole averages 49.8 dBA and the U.S. averages 52.0 dBA. Both are lower than Ravine Gardens because most of either area is rural land away from major roads.
Share of residents above 55 dBA
About 17.6% of Ravine Gardens 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, 24.3% of Ravine Gardens's footprint sits above 55 dBA, against a New Jersey average of 25.2% and a national average of 28.1%.
What This Means if You're Moving to Ravine Gardens
- 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 Monmouth County 6A Ii 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 34% of Ravine Gardens is under tree cover (much heavier than most neighborhoods), 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. Newark Liberty International's approach paths concentrate aviation noise to the north. Neighborhoods to the south of downtown show no measurable contribution from the airport.
