AI data centers face growing noise complaints from infrasound and industrial generators running continuously near residential areas

Communities near AI data centers report infrasound — frequencies below human hearing threshold — from cooling systems and gas turbines, with claims linking the phenomenon to headaches, insomnia, nausea, and anxiety. The Environmental and Energy Study Institute reported noise levels reaching as high as 96dB for 24 hours a day and seven days a week in surrounding areas.

On-site backup diesel generators and continuous-operation gas turbines generate noise reaching 105dB (louder than a snowmobile). Unlike backup generators that run occasionally, turbines powering off-grid data centers run continuously, and on-grid sites test backup generators for up to 50 hours annually, meaning noise can occur at unpredictable times.

Cooling accounts for nearly 40% of data center power use and is a major noise source. A single modern AI GPU consumes up to 3.7 MWh of power annually; with multiple GPUs per server rack, the scale of cooling fans deployed generates significant sound pollution.

Local governments have placed moratoriums on data center projects citing noise and infrasound issues. AI hyperscalers often build near existing infrastructure rather than remote sites, placing facilities closer to population centers where opposition is increasing.
