This is a large open space with small 'break spaces' (soft carpet covered cubicle walls left scattered around) that break up sound/spaces between different groups. They have the soft drop ceiling tiles to help absorb sound. The floors are carpeted.

There's really only so much you can do with a hundred people in a large open space-there's a constant background hum of people moving, shifting, eating, listening to music that you just can't get rid of
