Updated global acoustic standards for educational buildings have been fully implemented in 2026. Large teaching spaces such as auditoriums, multi-function halls and lecture rooms face persistent low-frequency reverberation, which cannot be sol...

Large public venues including auditoriums, gyms and multi-function halls have long been troubled by severe low-frequency reverberation. Ordinary porous acoustic materials can only absorb high-frequency noise, leaving muddy bass resonance and u...

Global educational infrastructure continues to optimize indoor acoustic standards, requiring large teaching spaces such as lecture halls, auditoriums and multi-function classrooms to effectively control mid-low frequency reverberation. Traditi...
