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 2,494 South East End residents, or 64.1%, live above that level. By land area, 62.6% of South East End is above 55 dBA.
Average noise levels for South East End residents, grouped by direction from the center of South East End. Southern South East End carries the highest population-weighted average; Eastern South East End carries the lowest. Just 27% of residents in Eastern South East End live in blocks above the EPA's 55 dBA threshold, a third of the share in Southern South East End.

QuietLoud
Southern South East End sounds about 107% louder than Eastern South East End to the human ear, a 10.5 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 Griggs St SE do you need to be?
Griggs St SE produces an estimated 55 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 34% of South East End sits under tree canopy (much heavier than most neighborhoods) and roughly 35% 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
Gerald R Ford International (GRR) sits southeast of South East End. 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 55 dBA on the map's Overall layer. Blocks on the opposite side of South East End, particularly to the northwest, show no measurable aviation contribution. Use the Aviation toggle on the map above to isolate the airport's footprint.
How Noise Is Distributed Across South East End
The bar chart below shows the share of South East End residents in each noise band. About 37% of residents live below the EPA's 55 dBA threshold, and roughly 12% live in blocks above 60 dBA. Long-term exposure in that range is linked to elevated stress hormones and cardiovascular risk.
How South East End Compares
South East End sits at the quieter end of the spectrum. Below: how South East End's average outdoor noise and share of residents above the EPA threshold compare with Alger Heights, Swan, Heartside-Downtown, and Belknap Lookout.
Average noise level (dBA)
South East End's 55.7 dBA pop-weighted average is at the quieter end of the spectrum. Michigan as a whole averages 49.3 dBA and the U.S. averages 52.0 dBA. Both are lower than South East End because most of either area is rural land away from major roads.
Share of residents above 55 dBA
About 64.1% of South East End 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, 62.6% of South East End's footprint sits above 55 dBA, against a Michigan average of 19.9% and a national average of 28.1%.
What This Means if You're Moving to South East End
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 Griggs St SE 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 34% of South East End is under tree cover (much heavier than most neighborhoods), 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. Gerald R Ford International's approach paths concentrate aviation noise to the southeast. Neighborhoods to the northwest 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.
