The Data Center Being Built in Elyria-Swansea is Getting Loud

The CoreSite data center in Elyria-Swansea is nearly complete, and some skeptical neighbors are already starting to see their concerns manifest at the 170,000-square foot facility. Early worries about environmental and noise pollution are starting to come to fruition, with nearby residents reporting low-frequency generator noises. One local science teacher is even using a grant to study the noise around the site, according to CPR News’ climate reporter Sam Brasch. So, we’re revisiting a conversation from last fall when host Bree Davies sat down with Brasch to talk through everything he had learned about AI data centers.
