low-frequency sound

The new limits on low-frequency sounds that industrial operations can emit won't apply to Amazon's data center because its building permits have been issued but they will apply to the data center that Microsoft will soon start building in Granger.

St. Joseph County Council President Bryan Tanner says he sympathizes with people living north of the Toll Road who might want to complain about low-frequency sound but it will not be possible to accurately measure sound from the data center when the Toll Road makes so much noise itself.

A St. Joseph County Council committee will consider new restrictions on low-frequency sound, the kind we feel rather than hear, that's emitted by industrially zoned operations like data centers.
