Johnson City, TN, is set to approve a $96,880 contract for a noise and vibration study to update its noise and zoning ordinances concerning data centers. The study follows public concerns over a potential Bitcoin mine's noise levels and aims to assess the impact of heavy manufacturing on the environment.

Conducted by a California company led by acoustic engineer John Matagos, the study will gather data from 10 sites across the city and propose solutions to city officials. Proposed changes to regulations are expected to be presented by late spring 2026, prior to the expiration of a moratorium on new businesses in the I-2 heavy industrial zone.
