Abstract
The design of the Pritzker Pavilion includes a number of innovative acoustic and audio elements. Two of these elements, the resilient orchestra riser system and the acoustic enhancement system, will be discussed in this presentation. Research previously presented to the ASA [Hoffman et.al., 141st meeting of the ASA) was used in the design of the orchestra riser system at the Pritzker Pavilion. This presentation discusses the field tests that were conducted to assess vibration transfer across the surface of the riser system. Comparison is made to previous research and anticipated results. Subjective evaluations by orchestra members will also be discussed. The acoustic enhancement system is a specialized audio system, separate from the main reinforcement audio system, based on LARES digital signal processing and a distributed loudspeaker approach. Different settings have been developed over time to provide varying decay signatures that are employed on a music‐program‐dependent basis. Impulse response measurements were taken of unamplified sound, the reinforcement system, and the combination of the reinforcement system with the enhancement system. Testing was conducted with faculty and students from the University of Nebraska.
