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. Traditional porous acoustic materials cannot target low-frequency standing waves, resulting in unclear teaching sound and poor sound field uniformity.
In 2026, grooved and perforated resonant acoustic panels have become the standard technical solution for educational space renovation. Based on Helmholtz resonance principle, the panels precisely absorb 250Hz–1000Hz low-frequency noise that dominates large teaching venues. Cooperated with rear cavity and acoustic cotton, the overall NRC reaches 0.90, greatly improving speech intelligibility.
With formal and elegant wood veneer appearance and stable fire-proof performance, resonant acoustic panels fully meet long-term public teaching usage requirements. Educational facility designers confirm that resonant acoustic technology will be fully popularized in newly-built and renovated campus projects in the next two years.
