Magnificent Masonry

Fig. 2. The original 4-ft thick masonry walls at St. Luke's Church were retained to provide the acoustic quality needed for the London Symphony Orchestra.

The interior of the new area (Fig. 3) includes massive brick wall construction (note the wall thickness through the specially designed acoustic windows at left).

Fig. 4. Masonry at the Detroit High School for the Performing Arts was used extensively for sound isolation and interior acoustic quality.

Fig. 5. Cast stone panels were designed to scatter sound at high frequencies in the Concert Hall at the Experimental Media and Performing Arts Center at Rensselaer Polytechnic Institute, Troy, N.Y.

A different cast stone panel shape (Fig. 6) was used on the side walls.

Fig. 7. The upstage wall at Strathmore Hall, Bethesda, Md., uses two rows of fully-grouted 8-inch block bonded together to create mass, and shaped to provide the appropriate sound reflection paths.

Two resilient, grout-filled block walls that separate rehearsal rooms are built on neoprene pads that “float” and achieve structural separation from the continuous slab beneath (Fig. 8).
