Acoustical treatment of broadcast studio and control room
SONEX ONE Panels and Baffles, PROSPEC Composite
To improve the sound quality of university television broadcast courses and resulting student programming at California State University, Dominguez Hills Campus, The university decided to upgrade the acoustics of the existing studios and control rooms. This was achieved with materials and products from pinta acoustic, which now allow for professional-quality broadcasts.
The universities academic television production facilities date back to at least the early 1970s and were orginally constructed to be used as a theater department facility. When the university needed television broadcast faciltieis, the space was revamped for that purpose. However, students and faculty struggled with sound reverberation and inconsistency in the space for many years, primarily because it was never treated with appropriate acoustical materials.
California State University, Dominguez Hills Three walls of the control room were treated with 1,000 square feet (93 square meters) of light gray SONEX One Panels. The fourth wall of the 20 feet by 15 feet by 18 feet room is composed of floor-to-ceiling windows covered with heavy drapes. Three walls of the broadcast studio were treated with 2,700 square feet (251 square meters) of SONEX One Panels. The wall between the two rooms was treated with 900 square feet (93 square meters) of PROSPEC Composite to reduce noise transmission from the studio into the control room. The 50 feet by 50 feet by 18 feet studio also was treated with SONEX One Baffles, individually suspended from the ceiling above the lights. The baffles absorb sound on both sides to reduce reverberation. All of the illbruck products installed were specified with a water-based acoustic coating for added durability and easy cleaning with a damp cloth.
