This ClearSonic ST2448 24" W x 48" L x 1.6" D Sorber sound absorption baffle is used as the side pieces for our small format LidPac isolation booth lid system used with our IsoPac G vocal isolation booth. The angled side helps the isolation booth lid match the curvature of your isolation booth. It is constructed of a lightweight rigid fiberglass panel covered in sound absorbing fabric, and, like all of our Sorber products, is effective at absorbing vibrations and sound waves to help lower reflections in a room.
