Design of a Sound Reinforcement System for Koerner Hall

Document Thumbnail

Built over three years, the 1,135-seat Koerner Hall is the jewel of the new TELUS Centre for Performance and Learning at the Royal Conservatory of Music in Toronto, Canada. Since its opening in September 2009, Koerner Hall's beautiful design, flexible performance characteristics and superb acoustics have been praised by critics and performers alike. The hall achieved the highest possible acoustic rating—N1—rendering it ideal for the finest acoustical performances of classical music, jazz, and world music. The incorporation of variable acoustics makes it equally well suited to amplified music, lectures, and film presentations. This Engineering Brief will review the process and design of the sound reinforcement system. It features an innovative and almost invisible 'voice-stick' to maximize intelligibility, rather than sound reinforcement. The system must provide coverage for the audience as to performers on and around the stage in an extremely intimate venue. Testing the design with a computer and mock-up will also be discussed.
