The amount of hard reflective surface and the focusing tendency of the vault form created unique acoustical problems that were resolved by making the brick work acoustically. The vault brick cores trap the sound. Albert Grabe, Masonry Contractor, laid the brick on plywood shoring then swept sand into the units cores. A lightweight concrete was poured over the brick to serve as backing. After removing the shoring, the face side was pointed up and cleaned with a light sand blasting. One third of the area above the brick has an absorptive blanket of fiberglass and in addition the north wall is a perforated screen functioning in a similar manner. The wood battens on the mezzanine railing are spaced apart, again backed by acoustical material.
The entire structure is a tribute to excellent design complimented by time tested materials and outstanding craftsmanship.
