AI data centers in residential areas are generating low-frequency sound that residents say causes physical discomfort even though it doesn't show up on standard decibel meters. Tom's Hardware and other outlets have documented these complaints from neighbors, though the specific health effects haven't been independently verified by medical researchers. The story is part of a broader pattern of data center infrastructure impacts — the same Georgia facility also secretly used 29 million gallons of water over 15 months before residents detected it through low water pressure.
