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 723 Spring Lake residents, or 19.5%, live above that level. By land area, 17.7% of Spring Lake is above 55 dBA.
Average noise levels for Spring Lake residents, grouped by direction from the center of Spring Lake. Central Spring Lake carries the highest population-weighted average; Western Spring Lake carries the lowest. Just 12% of residents in Western Spring Lake live in blocks above the EPA's 55 dBA threshold, a third of the share in Central Spring Lake.

QuietLoud
Central Spring Lake sounds about 61% louder than Western Spring Lake to the human ear, a 6.9 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 Monmouth County 18 Iii do you need to be?
Monmouth County 18 Iii produces an estimated 58 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 29% of Spring Lake sits under tree canopy (about average for cities) and roughly 37% 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 Spring Lake. 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.
How Noise Is Distributed Across Spring Lake
The bar chart below shows the share of Spring Lake residents in each noise band. About 78% 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 Spring Lake Compares
Spring Lake sits at the quieter end of the spectrum. Below: how Spring Lake's average outdoor noise and share of residents above the EPA threshold compare with Sea Girt, Neptune City, Bradley Beach, and Spring Lake Heights.
Average noise level (dBA)
Spring Lake's 51.9 dBA pop-weighted average is at the quieter 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 Spring Lake because most of either area is rural land away from major roads.
Share of residents above 55 dBA
About 19.5% of Spring Lake 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, 17.7% of Spring Lake'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 Spring Lake
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 18 Iii 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 29% of Spring Lake 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.
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.
