Center for Cinematic Arts Turns a Classroom into a Theater with Acoustics
Liberty University is the largest private non-profit university in the nation and the largest evangelical university in the world. The school offers over 229 programs of study, including an impressive Center for Cinematic Arts. The Center provides top-of-the-line production equipment for student use, and guest speakers including famous screenwriters. During a recent renovation, classrooms in the department were converted into theater screening rooms where students could be immersed in a film as well as instructed by resident professors. The
A/V equipment in each room would not reach its maximum potential, however, without the proper acoustical consideration.
Application Introduction
A new theater style screening room was near completion in Liberty University’s Center for Cinematic Arts in Lynchburg, Virginia. The rooms came equipped with an enormous screen, high-end projector, and a sound system for optimal sound quality.
The system, however, did not sound as good as it could have inside the classroom. The room was large and had bare, hard, parallel gypsum walls causing reverberation, reduced speech intelligibility and reduced clarity or sound effects and music.
Even when the A/V equipment was not being used, the instructor had trouble being understood by the students, and vice versa.
Treatment Provided
Acoustical Solutions, Inc. stepped in and provided a multifaceted solution to solve issues with reverberation and speech intelligibility. It was important that a comprehensive noise control treatment was provided, or the room would not function correctly and the audio-visual installation would be less than adequate.
Four inch thick acoustical insulation was first applied in the cavity behind the screen, creating in essence a giant bass trap to absorb excessive low frequency noise. Acoustone amplifier grille cloth was then used to cover frames for the speaker compartment below the screen, but still grant access to the compartment. This cloth is engineered for minimum interference and maximum sound reproduction.
2” thick AlphaSorb fabric-wrapped acoustical wall panels were mounted along the side walls and back wall to reduce noise and reverberation, while still keeping the room “live” with some ambience. In addition, curtains made of heavy, backed, sound absorbing fabric materials were custom made to hang on either side of the screen for acoustics and to complete the theatic atmosphere.
Results
The changes in the room’s sound were noticeable before the speakers were even turned on. Michael Gerringer, the Director of
Technical Production & Media Systems at Liberty stated as he clapped in the completed room: “Now that’s quiet!”
