Sound Management in Auditoriums needs to carefully done so as to minimise sound reverberations that hamper speech audibility and intelligibility. Both Auditorium Acoustics and Sound design need to be smartly balanced so as to provide the best auditory experience while minimising the total costs involved, be it the cost of acoustic materials or the power consumed by the sound systems. Below is a an example of sound management in an auditorium of a University.
Invertis University was established in 1998 and has eight different institutes under its umbrella. The university campus, known as Invertis village, is built on sprawling 95000 sq. metres campus on NH-24, Bareilly. The world class auditorium completed in 2008 has a two-tier structure and has a seating capacity of more than 2000. Considering its length and two-tiered structure, the sound system was to be designed so as to maintain speech audibility and intelligibility at the farthest end of the long auditorium. The best audio solution for such venues are line arrays that send sound waves farther than the traditional horn loaded loudspeakers, and with a more evenly distributed sound output pattern. Considering the best possible solution, we installed OHM's Lunaray Line Array Cabinets. Three arrays with four units each were installed at the top front of the stage. For base, two TRS-118H subwoofers were installed. Its high efficiency horn loading brings the advantage of less amplification requirement. Also, considering the clients requirement for cinema surround sound, twenty four OHM LB3 surround speakers were installed along the walls and at the back of the auditorium. Stage Monitors System included two TRS112s for the performers.
