Billy Finn can hear it through closed windows. Over the television. On his porch, where a sound meter once registered 63.9 decibels — roughly the volume of a dishwasher someone switched on in 2022 and never turned off. Finn lives in Dowagiac, Michigan, directly across from a 30-megawatt data center operated by Alliance Cloud Services, a Hyperscale Data Inc. subsidiary. He describes the noise as “like a jet engine” that never quits. Now the company wants to expand the facility more than tenfold, to 340 megawatts.
The Sound Nobody Signed Up For
Chronic 60–70 dB noise from cooling fans has triggered a federal lawsuit and forced Dowagiac to rewrite its noise rules.
That hum your refrigerator makes at 2 a.m.? Multiply it by an industrial cooling array and remove the off switch permanently. Acoustic health research summarized by MLive finds these levels won’t destroy your hearing outright — but they will contribute to chronic stress, sleep disruption, and headaches, the slow-drip damage that compounds quietly over time. The facility’s tonal noise — a distinct mechanical pitch rather than broadband white noise — can also warrant an additional 5 dB penalty in regulatory assessments, because the human brain finds a sustained tone more irritating than equivalent-volume broadband sound.
Porch measurements near residences clocked approximately 63.9 dB. The culprits are:
- cooling fans
- HVAC chillers
- condenser units running 24 hours a day, every day of the year
A federal class-action lawsuit filed against Alliance Cloud Services alleges nuisance and negligence, seeking to represent all owner-occupants and renters within one mile of the facility. The City of Dowagiac revised its noise ordinance in March 2026 — years after the center began operating.
“Like the sound of a jet engine,” Billy Finn told reporters, describing life next to AI infrastructure most people only encounter as an abstraction called “the cloud.”
A Tenfold Expansion, and the Bill You’ll Pay
Hyperscale’s growth plans collide with Michigan’s 16-gigawatt data center pipeline and the real prospect of rising electric rates.
Scaling from 30 to 340 megawatts isn’t a renovation — it’s a transformation of an entire neighborhood’s acoustic environment. As of the latest petition filings, no formal development requests had been submitted to the city, raising the genuine possibility that expansion advances through utility arrangements and tax incentives before residents get a public hearing. Michigan’s two largest utilities, DTE and Consumers Energy, reportedly carry roughly 16 gigawatts of data center projects in their development pipelines, according to Planet Detroit.
The economics deserve scrutiny:
- Douglas Jester of 5 Lakes Energy has warned that a single 1-gigawatt data center could push residential electric rates up 5 to 10 percent without protective policies in place.
- The World Resources Institute reports a modern AI data center can consume as much power as 100,000 homes — while employing a skeleton crew of permanent workers.
“Rapid expansion is often happening with limited public information about the long-term impacts.” — WRI analysts
Factories and power plants got zoned away from neighborhoods decades ago precisely because of noise and environmental damage. Data centers, sold as clean digital infrastructure, slipped past that same scrutiny — like a Terms of Service agreement nobody reads until something breaks. Dowagiac’s lawsuit and hastily revised ordinance may well become the template other towns reach for before the hum ever starts.
