Data Center Noise Is Fan Low-Frequency Hum That dBA Rules Barely Measure
CurieuxExplorer · x · 2026-09-25
A detailed explainer on data center noise: a GB300 NVL72 rack draws 140 kW that exits as heat, with Amazon's Tanner Way campus running 400+ rooftop exhaust fans about 600 feet from homes. Prince William County's 55 dBA night limit is met on paper, but fan/transformer low-frequency tones (e.g., 73 Hz) travel far and penetrate walls — and the dBA scale barely registers low frequencies.
