Cerami primarily consulted on the prevention of sound transfer between adjacent exhibits within the museum via interconnected piping, ductwork, or other conduits. Our first step was to review the exhibits’ layouts and make recommendations for the overall design and acoustical treatments in these spaces.
The Panamarama exhibit is designed to include seventeen film and video projectors–some of them located below the floor. To determine what acoustical design measures were required to prevent sound transmission to the other exhibits, we created an acoustical model of the space. We were then able to test the dimensions and finishes required to prevent sound transmission to the exhibits below and adjacent to it. One solution we produced was the use of an acoustic tunnel to separate this exhibit from others without the addition of doors that would close off the space.
The Worlds Collide exhibit features an array of suspended birds with speakers providing sound effects, but the acoustics of the room caused these sound effects to reverberate, and thus, caused sounds to be unintelligible. Cerami’s acoustic team found that these problems were caused by surfaces within the exhibit being too hard and the placement of the speakers too high. While these problems could have been solved by the selection of new speakers, we instead provided the more cost-effective solution of simply repositioning the existing speakers around the edges of soft-fitted spaces.
