Data Center Noise Reaches Court

Residents near Microsoft’s Fairwater campus in Mount Pleasant, Wisconsin, and Hyperscale Data’s facility in Dowagiac, Michigan, are pursuing lawsuits or regulatory action over persistent data center noise.

The disputes focus on sound from cooling systems, fans, generators, and mining equipment, with residents citing sleep disruption, property impacts, and measurements they say fail to capture low-frequency noise. Operators and local officials report mitigation or enforcement steps, but the cases leave unresolved questions about acceptable sound levels, monitoring methods, and how expansion plans will affect nearby neighborhoods.
