Residents of Dowagiac, Michigan, just filed a lawsuit against a data center that allegedly generates a high-pitched whining sound — and has done so 24/7 for the past two years.

The data center, which is owned by Alliance Cloud Services LLC, a subsidiary of Hyperscale Data, used to be an industrial building that sat behind a row of pine trees across the street from the most affected residents, according to ABC-affiliateWXYZ. The site started development in 2018 and was eventually turned into a cryptocurrency mining center in 2021. But in 2024, something changed drastically when the building started emitting noise pollution around the clock. Residents say it sounds like a vacuum cleaner in their living room, and the company has offered to buy up homes from unhappy residents.
