Quiet office to normal conversation
Northern Hopkins Fitch Grant sounds about 57% louder than Western Hopkins Fitch Grant to the human ear, a 6.5 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 do you need to be?
produces an estimated 68 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 16% of Hopkins Fitch Grant sits under tree canopy (about average for neighborhoods) and roughly 43% 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 Hopkins Fitch Grant. 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 Hopkins Fitch Grant
The bar chart below shows the share of Hopkins Fitch Grant residents in each noise band. About 60% of residents live below the EPA's 55 dBA threshold, and roughly 6% live in blocks above 60 dBA. Long-term exposure in that range is linked to elevated stress hormones and cardiovascular risk.
How Hopkins Fitch Grant Compares
Hopkins Fitch Grant sits at the quieter end of the spectrum. Below: how Hopkins Fitch Grant's average outdoor noise and share of residents above the EPA threshold compare with Colemans Daytona, Town of Blake, Bethune Grant, and Craig Farms.
Average noise level (dBA)
Hopkins Fitch Grant's 53.9 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 Hopkins Fitch Grant because most of either area is rural land away from major roads.
Share of residents above 55 dBA
About 35.4% of Hopkins Fitch Grant 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, 46.9% of Hopkins Fitch Grant'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 Hopkins Fitch Grant
- 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 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 16% of Hopkins Fitch Grant is under tree cover (about average for 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.
