Prior to the renovation, the large open space of Hall 5A had a reverberation time in excess of eight seconds at 1 kHz. With acoustic treatment of the walls reducing reverberation to a more manageable 2.7 seconds, CAL has proven to be a far superior solution compared to its former ceiling system.
"With its precise beam steering technology, CAL has greatly reduced the sound reflected from the ceiling," explains Min Ho Jang, director of BEXCO's Exhibition Centre 2. "Even without costly acoustic treatment for the ceiling areas, CAL allows us to reproduce high-quality sound to the audience with a very natural feeling. The speech transmission index has also greatly improved."
The new CAL 32 loudspeakers were provided, installed, and configured by Sovico, Meyer Sound's Korean distributor. Busan-based Bone Engineering provided architectural acoustics and electro-acoustic design for the space.
The renovation of Hall 5A also included the addition of a Behringer X32 digital mixer and a BSS BLU-100 signal processor.
