How Loud Are Data Centers? Some Are Quiet, Others Sound Like A Freeway

Communities are increasingly pushing back against the proliferation of data centers, citing concerns over noise, energy costs, water usage, and light pollution. Residents have reported experiencing an "unbearably loud hum," with some comparing the noise from air-cooled data centers to living next to a busy freeway, reaching 60-80 decibels. These facilities rely on numerous fans for cooling in areas lacking freshwater access. In contrast, water-cooled data centers are quieter, producing 40-60 decibels, comparable to a refrigerator or dishwasher. While proponents argue that data centers bring jobs and economic benefits, opponents worry about the environmental impact, rising energy costs, and potential decrease in property values due to large industrial buildings. The article highlights that regions with abundant freshwater and existing infrastructure are considered ideal for data center development.
