At one startup they got 2 adjacent open plan rooms at a WeWork. One was the quiet room, the other was not. I worked in the quiet room and it was really nice, like a library late at night. I’d chat with the guy sitting next to me on Slack. And if we needed to discuss something, we’d all move to a meeting room or the loud room. The CEO could not understand how we could prefer the quiet room. He’s a sales guy who chatters constantly. To him the silence was miserable, like a tomb. For us it was very productive and we could easily take a break to chat on our schedule.
