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 solved by ordinary porous acoustic materials.
Grooved and perforated resonant acoustic panels have become the designated professional solution for educational renovation projects. Based on the Helmholtz resonance principle, the structural design precisely absorbs stubborn 250Hz–1000Hz mid-low frequency standing waves. Matched with rear air cavities and acoustic backing cotton, the overall NRC reaches 0.90, greatly improving speech clarity and sound field uniformity.
With elegant wood grain finish, stable fire resistance and impact resistance, resonant acoustic panels perfectly adapt to long-term public teaching scenarios and are widely promoted in global campus new-build and renovation projects.
