This question already has an answer here:
I have a desk next to a co-worker who has dial-in meetings all day. Often she stands up and walks around, and at times, gets very loud when getting involved in the meeting. I work in developing software, and really need to focus on what I am doing to be successful and efficient, but I find I can't. I put in headphones and listen to music, but while that drown out most of the noise, I have to turn it up loud, and doesn't help my focus at all. I'm not sure what I can do.
There are plenty of meeting rooms that she could go to, but I'm sure it is more comfortable to stay at your desk. I am sure she'd take offense at the suggestion. Not to mention I am a contractor, and she is full time. If I complain, it would well just be a ticket out the door for me.
