I remember the first time I was in an open office. I was flabbergasted. We'd all get on a call so we could talk to some remote vendor. Other people would have their mics on, so I'd hear my own voice repeated and delayed through the Zoom call. I could barely talk, and barely hear anyone. It was a self-evidently terrible decision that everyone was just going along with. Sometime later we were moved to a different open office space. It was deafeningly loud in there, and I eventually discovered that there was a white noise machine on the ceiling above every single employees head. Apparently this was meant to help with the open office design, but it did the opposite: much like a busy cafeteria, everyone had to shout over top the all the extra noise in the room. (the combined sound of about 100 white noise speakers + the sound of about 100 employees talking or working) Again, such a stupid decision I can barely understand how someone could set it up this way. I eventually just waited 'til no one was around and unplugged most of the speakers. It was a huge improvement, and no one complained.
