Thailand says new data centers can't be louder than a hair dryer — but will the new 70dB limit actually help those living nearby?

Thailand has implemented new environmental regulations targeting data centers, focusing on three key areas: noise pollution, heat emissions, and water consumption. Among these requirements, the government has set a 70-decibel noise limit for facilities operating uninterruptible power supply systems. This noise level is equivalent to that of a household hair dryer, though actual measurements may vary depending on the specific equipment and operating conditions.

Whether this restriction will provide significant relief to nearby residents remains uncertain, as it depends on factors such as the location of measurements, the specific operating circumstances, and the effectiveness of enforcement measures. Additionally, Thailand has established temperature limitations, requiring data centers to keep any temperature increases around their facilities within a 1 to 2-degree Celsius range.

Furthermore, operators must implement water recycling systems to manage cooling water and ensure wastewater meets testing standards before discharge. These measures aim to balance Thailand's growing technology sector with environmental considerations, as the country seeks to attract international investment in AI-related projects while safeguarding the resources of local communities.
