Neighbors raise concerns about noisy data center in Loudoun | NBC4 Washington

Loudoun County residents are reporting a persistent and loud droning noise from a data center in the Ashburn area, prompting an investigation by local authorities. News4's Julie Carey reported from Loudoun County Parkway near Waxpool Road, where sound measurements inside the facility reached 90dB, a level considered high enough to require ear protection for sustained exposure. Residents have posted on apps like Ring, describing a constant low-frequency hum that can be heard up to five miles away in Sterling. Some residents likened the noise to a helicopter hovering continuously. One resident also reported seeing black smoke emanating from the data center. The facility has been identified as one of several Cloud HQ data centers in the vicinity. A Loudoun County spokesman confirmed that zoning enforcement has received a complaint regarding the noise and will be investigating. News4 attempted to contact Cloud HQ for comment on the cause and expected duration of the noise but had not received a response.
