You can use our 3/8" Pre Cut Heavy Duty Rubber Rolls as a sound cushioning for flooring in an AV booth. These rolls would not be the best solution for this, but they would work. If you wanted to get something that would work better for sound absorption, we would recommend on our rubber underlayments. These rolls are very solid and would not warp or breakdown if chairs were rolling over them. You don't have to glue these rolls. You can loose lay the rolls, use double-sided tape, or you can glue the rolls down.
