Oh, please. A trip to Wikipedia would have told you that[1]:
> A systematic survey of research upon the effects of open-plan offices found […] high levels of noise, stress, conflict, high blood pressure and a high staff turnover. The noise level in open-plan offices greatly reduces productivity, which drops to one third relative to what it would be in quiet rooms.
> Open-plan offices have frequently been found to reduce the confidential or private conversations which employees engage in, and to reduce job satisfaction, concentration and performance, whilst increasing auditory and visual distractions.
Further, open office plans spread disease more readily[2]:
> elevated risks [for disease] were found among employees in all three traditional open-plan offices
An open office floor plan robs you of the ability to control the noise level in the environment. There is literally no way for me to convince enough of my coworkers that they should:
* Either take their phone with them, or silence it if leaving it at your desk.
* Stop having meetings in the aisle immediately next to my desk.
* If you're going to video conference in the meeting rooms, and have the other end at full volume, close the damn door. If you don't know enough about video conferencing to understand what a feedback loop is, and want to spend the first 10 minutes of the meeting generating them, close the damn door. Stop looking at me like I'm rude when I close the door for you.¹
Calling people out gets a typical "oh, sorry", but not an actual change in behavior.
Maybe it encourages me to talk to the team nearby. Maybe. But is it worth the losses? No. (The team next to me is sales. They're not bad people, but they are fairly noisy. (And I'm sure they'd say the same of us, in fact!))
