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 unclear speech sound.
In 2026, resonant grooved and perforated acoustic panel technology is widely promoted in public construction renovation. Based on Helmholtz resonance principle, these professional acoustic structures target 250Hz–1000Hz mid-low frequency standing waves that are hard to eliminate. Cooperated with rear air cavities and acoustic filling materials, the overall NRC reaches 0.90, realizing full-band balanced noise reduction.
With stable fire resistance, impact resistance and formaldehyde-free features, resonant acoustic panels have become the professional standard solution for educational, cultural and sports public buildings globally.
