Dreamhack Austin not soundproofed?

Soundproofing gaming booths is extremely essential in order to maintain the concentration of the professional players. The sole purpose of the booth is to provide a very secluded environment so that players can concentrate on their gameplay.

It was definitely a very cumbersome experience and one that put Gamers2 at a disadvantage.
