Usually not by itself. If you do not have acoustically absorbent treatments to the sides and behind your drummer, you may end up with a very roomy sounding drum set in the audience areas. We strongly recommend the use of sound absorbing panels on the lower half of the ClearSonic Panels as well as panels behind and beside your drummer to soak up all that excess acoustic energy. IsoPac systems that utilize the lid system provide the most reduction in sounds.
