The exclusive film and television space of the group headquarters (used by leaders for leisure reception), with a project area of 89m². The construction material a few years ago is perforated sound-absorbing panels uniformly. After a three-month construction period, through repeated adjustments to the plan, the audio and video effect reverberation time was achieved at 0.48 seconds, especially for low-frequency accumulation in the corners of the room. Look back at this project a few years later. Acoustic treatment has been fully considered in the design process. The acoustic simulation calculation and modeling of the entire space, sound wave reflection, and sound field uniformity can be achieved through the existing new technology. The wall and top surface can be based on modeling data. The production of fast-installed acoustic structure, about 7 days of construction, has reached the best acoustic environment of environmental protection, speed and beauty. (The new technology adopts the SWAP sound absorption module of prestige acoustics quick installation adjustable acoustic structure)
