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 781 Keego Harbor residents, or 47.1%, live above that level. By land area, 51.1% of Keego Harbor is above 55 dBA.
Average noise levels for Keego Harbor residents, grouped by direction from the center of Keego Harbor. Northern Keego Harbor carries the highest population-weighted average; Southern Keego Harbor carries the lowest. Just 28% of residents in Southern Keego Harbor live in blocks above the EPA's 55 dBA threshold, about two-thirds of the share in Northern Keego Harbor.

QuietLoud
Northern Keego Harbor sounds about 39% louder than Southern Keego Harbor to the human ear, a 4.8 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 Orchard Lake Rd do you need to be?
Orchard Lake Rd produces an estimated 67 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 14% of Keego Harbor sits under tree canopy (lighter than most cities) and roughly 48% 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
Detroit Metro Wayne County (DTW) sits south of Keego Harbor. 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 Keego Harbor, particularly to the north, show no measurable aviation contribution. Use the Aviation toggle on the map above to isolate the airport's footprint.
How Noise Is Distributed Across Keego Harbor
The bar chart below shows the share of Keego Harbor residents in each noise band. About 48% of residents live below the EPA's 55 dBA threshold, and roughly 16% live in blocks above 60 dBA. Long-term exposure in that range is linked to elevated stress hormones and cardiovascular risk.
How Keego Harbor Compares
Keego Harbor sits the highest among the peer group. Below: how Keego Harbor's average outdoor noise and share of residents above the EPA threshold compare with Sylvan Lake, Orchard Lake Village, Bingham Farms, and Salem.
Average noise level (dBA)
Keego Harbor's 55.0 dBA pop-weighted average is the highest among the peer group. Michigan as a whole averages 49.3 dBA and the U.S. averages 52.0 dBA. Both are lower than Keego Harbor because most of either area is rural land away from major roads.
Share of residents above 55 dBA
About 47.1% of Keego Harbor 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, 51.1% of Keego Harbor'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 Keego Harbor
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 Orchard Lake Rd 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 14% of Keego Harbor is under tree cover (lighter than most 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.
Airport noise is directional. Detroit Metro Wayne County's approach paths concentrate aviation noise to the south. Neighborhoods to the north 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.
