I've struggled with working in similar environments. For one year (in the last 15) I had my own office and was the most productive during that time.

I'm in an open-office now and use light over-ear headphones (I found the Bose Bluetooth ones good) and listen to white noise (by playing with the frequencies you can usually drown out what's bothering you). Of course my preference would be a quiet space, but this white-noise strategy has worked well for several years now.
