The document discusses the process of creating a 1/10th scale acoustic model of the planned 1,600 seat symphony hall for the new Kauffman Center for the Performing Arts in Kansas City. Acoustic designer Yasuhisa Toyota oversaw the testing of the model, which cost tens of thousands of dollars to create. The model contains 1,600 felt-covered "dummy head" replicas of audience members to simulate absorption and reflection of sound. Multiple tests are conducted using synthesized taps to identify undesirable echoes that need to be addressed in the hall's design.
