Google has team offices for some teams. My first year here my team was split in two 5-person offices with doors. For the last year we were in an open office space. Soon we're moving again and some of us will be in team offices again of 3-4 people. I don't know the percentage of team offices vs open offices across the company though.

Also, since moving into our current building they've added sound-resistant walls and barriers in various places which has helped significantly.

(Speaking for myself, as a happy employee.)
