This map shows modeled outdoor noise across Midtown 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 596 Midtown residents, or 64.1%, live above that level. By land area, 45.8% of Midtown is above 55 dBA.
54.2% below 55 dBA

Noise by Part of Midtown
Average noise levels for Midtown residents, grouped by direction from the center of Midtown. The highest population-weighted average is in northern Midtown; the lowest is in southern Midtown, where just 14% of residents live in blocks above the EPA's 55 dBA threshold, a third of the share in the loudest section.

Quiet office to normal conversation
To the human ear, noise in northern Midtown sounds about 59% louder than in southern Midtown, a 6.7 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 C St (anchorage) do you need to be?
C St (anchorage) produces an estimated 71 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 0% of Midtown sits under tree canopy (about average for neighborhoods) and roughly 0% 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
Ted Stevens Anchorage International (ANC) sits west of Midtown. The U.S. Department of Transportation models aviation noise around this airport from federal traffic data, 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 Midtown, particularly to the east, show no measurable aviation contribution. Use the Aviation toggle on the map above to isolate the airport's footprint.
How Noise Is Distributed Across Midtown
The bar chart below shows the share of Midtown residents in each noise band. About 42% of residents live below the EPA's 55 dBA threshold, and roughly 5% live in blocks above 60 dBA. Long-term exposure in that range is linked to elevated stress hormones and cardiovascular risk.
How Midtown Compares
Midtown sits the lowest among the peer group. Below: how Midtown's average outdoor noise and share of residents above the EPA threshold compare with tudor-area-anchorage-ak, Rogers Park, Mountain View, and Fairview.
Average noise level (dBA)
Midtown's 54.8 dBA pop-weighted average is the lowest among the peer group. Alaska as a whole averages 46.7 dBA and the U.S. averages 52.0 dBA. Both are lower than Midtown because most of either area is rural land away from major roads.
Share of residents above 55 dBA
About 64.1% of Midtown 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, 45.8% of Midtown's footprint sits above 55 dBA, against a Alaska average of 11.4% and a national average of 28.1%.
What This Means if You're Moving to Midtown
- 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 C St (anchorage) 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 0% of Midtown is under tree cover (about average for neighborhoods), and the dominant land cover is . 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. Ted Stevens Anchorage International's approach paths concentrate aviation noise to the west. Neighborhoods to the east of downtown show no measurable contribution from the airport.
