How a Bitcoin Mine's Constant Hum is Disturbing Life in a Small Texas Town

The Impact of Bitcoin Mining in Granbury, Texas

In 2022, a new bitcoin mining facility opened just outside the rural town of Granbury, Texas. Since then, a constant hum has tormented the town’s residents. According to Andrew Chow, a technology correspondent at Time, the noise has been compared to that of a vacuum, a lawn mower, or even sitting on a tarmac.

Health Issues Reported by Residents

Residents have reported various ailments, including tinnitus, severe migraines, vertigo, and cardiovascular issues, attributing these symptoms to the noise from the mine.

The Noise Level

The noise level recorded by local authorities has been alarming, often exceeding 90 decibels, which is not sustainable for human exposure on a 24/7 basis.

Understanding Bitcoin Mining

Bitcoin mines operate as large computer server farms with thousands of computers that require cooling fans. While many are located in remote areas, the proximity of the Granbury mine to residential areas has raised concerns about sound management.

Company Response to Noise Complaints

The company operating the mine, Marathon, has expressed intentions to be a good neighbor by replacing noisy fans and considering immersion cooling methods. However, they have not addressed potential health impacts. Meanwhile, there is a push within the bitcoin mining industry to reduce regulations surrounding noise ordinances.

Residents' Limited Options

Residents of Granbury face significant challenges. Texas law restricts the ability to create new noise ordinances outside city limits. Legal action is an option, but it could take months or years to resolve, leaving residents feeling that their lives have been severely affected by the continuous noise.
