Most open offices I have worked in have the din of idle banter, or the sound of hushed conversations, but have unwritten rules about noise and rampant interruptions. The din is still disrupting, resulting in a requirement for headphones which also serve as a do not disturb sign.
The fishbowl, where I work out of now seems to not follow these rules. Few will ever interrupt you since we are all working on our own thing, but people will still think it’s ok to be on calls half the day, which since are generally voip, people believe they need to talk at twice their normal volume. Loud team meetings are also not uncommon.
It’s rude and annoying.
