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 1,709 Little Falls residents, or 15.3%, live above that level. By land area, 19.6% of Little Falls is above 55 dBA.
Average noise levels for Little Falls residents, grouped by direction from the center of Little Falls. Eastern Little Falls carries the highest population-weighted average; Central Little Falls carries the lowest. Just 2% of residents in Central Little Falls live in blocks above the EPA's 55 dBA threshold, a fifth of the share in Eastern Little Falls.

QuietLoud
Eastern Little Falls sounds about 83% louder than Central Little Falls to the human ear, a 8.7 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 Passaic County 631 do you need to be?
Passaic County 631 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 35% of Little Falls sits under tree canopy (about average for cities) and roughly 42% 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 Little Falls. 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
Newark Liberty International (EWR) sits south of Little Falls. 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 Little Falls, particularly to the north, show no measurable aviation contribution. Use the Aviation toggle on the map above to isolate the airport's footprint.
How Noise Is Distributed Across Little Falls
The bar chart below shows the share of Little Falls residents in each noise band. About 71% of residents live below the EPA's 55 dBA threshold, and roughly 4% live in blocks above 60 dBA. Long-term exposure in that range is linked to elevated stress hormones and cardiovascular risk.
How Little Falls Compares
Little Falls sits at the louder end of the spectrum. Below: how Little Falls's average outdoor noise and share of residents above the EPA threshold compare with Cedar Grove, Woodland Park, Verona, and Upper Montclair.
Average noise level (dBA)
Little Falls's 51.5 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 Little Falls because most of either area is rural land away from major roads.
Share of residents above 55 dBA
About 15.3% of Little Falls 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, 19.6% of Little Falls'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 Little Falls
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 Passaic County 631 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 35% of Little Falls is under tree cover (about average for cities), 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. Newark Liberty International's approach paths concentrate aviation noise to the south. Neighborhoods to the north 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.
