Abstract
The room acoustic design of the Tokyo International Forum centered around the four performance halls: the convention center, the atrium, and the large multi-use meeting/dining halls. This paper will describe the program use of each space and the acoustic criteria developed to meet these requirements. Major emphasis will be placed on Hall A, a 5000-seat congress hall that was to be used to unamplified symphonic concerts and operas as well as highly amplified Broadway musicals and rock concerts, and Hall B, a 1500-seat classical music hall and piccolo opera house that also would be used for conferences and popular entertainment. A unique architectural feature of Hall B is the first design and installation of a Concert Hall Shaper, a device that enables a proscenium theatre with a stagehouse to be converted to a single acoustic volume for events such as symphony concerts requiring a longer reverberation time. Hall C, an extremely flexible space for fashion shows, summit meetings, and large receptions, and Hall D, another versatile space for theater, recitals, and live television productions, will also be described.
