My co-supervisor (2nd supervisor) comes to the office where I work to help her (main) Ph.D. students. The noise distracts my work. I find it unprecedented. Why not help her students in her own private office, instead of coming to the shared office space!?
I am not sure how to resolve this issue. Shall I message her, mention the issue to her students or to a superior academic, or change office?
Like it or not, there is a lot of hierarchy in academia and she has helped me in the past. I don't want to break relationships. In addition, I know I am not the only in the office who has noise issues.
What would be the diplomatic way to have a quiet office space?
Edit & Update:
1) Noise canceling earbudsor headphones are good and I have tried they do help, but to be honest if you want to concetrate to carry a task it's hard to maintain focus with loud volume.
2) I believe I have a common understanding with most of you guys. If there is a small chat in the office is fine but if it's a meeting more than 30 mins they should find a room. In my case, the co-supervisor helped her student for almost the whole day... And as I mentioned in the comment section from what I am aware she has an available office and there are plenty of meeting rooms in the Uni. If it's the computer thing they have laptops...
3) Thank you everyone for your support and suggestions, hope you are getting well with your offices. As mentioned from you, there cannot be a perfect office but at least have some common understanding I guess.
