This map shows modeled outdoor noise across Chesapeake Beach at 100-meter resolution, combining road, aviation, and rail sources. Green areas measure below 45 dBA. Orange and red exceed the EPA's 55 dBA outdoor threshold linked to long-term health effects. Use the layer toggles to view each source on its own or all together.

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 1,253 Chesapeake Beach residents, or 17.2%, live above that level. By land area, 35.3% of Chesapeake Beach is above 55 dBA.

Noise by Part of Chesapeake Beach
Average noise levels for Chesapeake Beach residents, grouped by direction from the center of Chesapeake Beach. Eastern Chesapeake Beach carries the highest population-weighted average; Western Chesapeake Beach carries the lowest. Just 0% of residents in Western Chesapeake Beach live in blocks above the EPA's 55 dBA threshold, a fifth of the share in Eastern Chesapeake Beach.

Quiet suburban street at night
Eastern Chesapeake Beach sounds about 155% louder than Western Chesapeake Beach to the human ear, a 13.5 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 64 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 53% of Chesapeake Beach sits under tree canopy (heavier than most cities) and roughly 20% 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
Ronald Reagan Washington Ntl (DCA) sits northwest of Chesapeake Beach. 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 Chesapeake Beach, 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 Chesapeake Beach
The bar chart below shows the share of Chesapeake Beach residents in each noise band. About 89% of residents live below the EPA's 55 dBA threshold, and roughly 1% live in blocks above 60 dBA. Long-term exposure in that range is linked to elevated stress hormones and cardiovascular risk.
How Chesapeake Beach Compares
Chesapeake Beach sits the highest among the peer group. Below: how Chesapeake Beach's average outdoor noise and share of residents above the EPA threshold compare with Dunkirk, Owings, Sunderland, and Lothian.
Average noise level (dBA)
Chesapeake Beach's 49.0 dBA pop-weighted average is the highest among the peer group. Maryland as a whole averages 52.3 dBA and the U.S. averages 52.0 dBA. Both are lower than Chesapeake Beach because most of either area is rural land away from major roads.
Share of residents above 55 dBA
About 17.2% of Chesapeake Beach residents live in blocks where outdoor levels exceed the EPA's 55 dBA threshold. That's more than any of its peer group. Measured by land area instead, 35.3% of Chesapeake Beach's footprint sits above 55 dBA, against a Maryland average of 32.9% and a national average of 28.1%.
What This Means if You're Moving to Chesapeake Beach
- 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 53% of Chesapeake Beach is under tree cover (heavier than most cities), and the dominant land cover is deciduous forest. 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. Ronald Reagan Washington Ntl's approach paths concentrate aviation noise to the northwest. Neighborhoods to the southeast of downtown show no measurable contribution from the airport.
