Nestled in Foshan's New City District, the 1,200-seat auditorium at the Sino-European Center underwent a transformative acoustic upgrade. Featuring a 15.8m deep, 39.5m wide stage, and tiered seating, this multifunctional space posed unique challenges necessitating meticulous acoustic engineering.
Acoustic Analysis:
- The expansive space risked echo and extended reverberation, potentially affecting speech clarity.
- Large flat surfaces could induce localized reflections, resulting in prolonged echoes.
- Limited low-frequency absorption might lead to masking effects and compromised clarity.
- Extended sound paths created frequency response imbalances.
- Varied height levels increased the risk of undesirable phenomena like whistling.
Acoustic Solutions:
- Ceiling: Curved design with 30mm thick GRG material for diffusion and aesthetics.
- Walls: Wooden perforated structures strategically placed for diffusion and absorption.
- Sound Gates: Wooden perforated absorption structures at entrances to minimize external noise.
Acoustic Renovation Impact:
- Achieved a reverberation time averaging 1.35s at 500Hz, meeting design specifications.
- Eliminated undesired sound effects like echoes and vibrations.
- Improved early reflections for a more pleasing auditory experience, accommodating a larger audience.
