Class Action Lawsuit Against Giant Microsoft AI Data Center in Wisconsin Due to Noise

The construction and operation processes of artificial intelligence data centers are often a subject of debate due to their massive energy consumption and the depletion of local water resources. However, for residents living in Sturtevant, Wisconsin, the biggest problem is extreme noise pollution that is incredibly difficult to eliminate. Local residents have filed a class action lawsuit against Microsoft's $7.3 billion Fairwater facility, located south of Milwaukee. Described by the company's CEO Satya Nadella as "the world's most powerful AI data center," this massive facility is expected to produce 865,000 tokens per second. Residents have resorted to legal action, claiming that this massive technology investment 严重影响 their peace and quality of life.

The group represented by the three citizens who filed the lawsuit includes thousands of households living just 1.5 miles (approximately 2.4 kilometers) from the facility and covers the Mount Pleasant area. The lawsuit petition emphasized that the sound emitted by the facility is not only excessively loud but also constant and felt everywhere. The plaintiffs complain that Microsoft failed to build adequate acoustic barriers, curtains, or walls to absorb, mitigate, or prevent the sound from spreading outside the facility. In fact, one local resident highlighted the severity of the situation by stating that they had to change their work shift just to be able to sleep at night. This situation clearly demonstrates the human costs of large technology infrastructure projects on local communities.

In addition to the noise problem, local residents are also greatly disturbed by the heavy dust and traffic caused by the data center's construction activities. Especially the extreme light pollution emitting from the facility at night has completely changed the neighborhood's night sky. Residents, stating that they cannot even see their houses when returning to town, say that before the facility, they had a dark sky full of stars, but now they only see bright artificial lights. These intense lights surrounding their living spaces negatively affect both the region's natural ecosystem and people's nighttime rest routines. All these environmental and physical impacts have turned the existence of the data center into a complete nightmare for the local population.

On the other hand, it appears that Microsoft is making efforts and taking steps to fix the situation. In a detailed blog post published on its community website, the company announced that its engineers have taken various measures to solve the problem. In a statement made on 18 Haziran, it was stated that the applied methods completely solved the problem and that additional sound-reducing components would be implemented in the coming months. According to the company's background information, Microsoft claims that the issue was noticed in Nisan and that the sound was not expected to travel this far. It is claimed that the source of the problem was cooling fans operating at very high speeds, and that the speeds of these fans have now been adjusted.

Despite this, the fact that the class action lawsuit was filed on 1 Temmuz shows that the problem was not fully solved as Microsoft claims, or that the distance between the facility and residential areas has rendered the problem unsolvable. Because some residents in the Mount Pleasant area live directly across from the data center campus. It is also a noteworthy detail that this land was designated as a heavy industrial area for Foxconn in 2017 before being sold to Microsoft. Moreover, the fact that Wisconsin laws do not allow changing or repealing current regulations, and that this right is only granted to cities and not towns, weakens the local population's hand. This tension between the infrastructure needs of developing AI technologies and the living rights of local communities is considered a harbinger of many similar legal battles in the future.
