Silicon-crystalline sand spatial sound absorber

The Silicon-crystalline Sand Spatial Sound Absorber is a high-end inorganic noise reduction component jointly developed by Bafang Acoustics and Tsinghua University. Designed as a suspended acoustic device, it features a dense micropore structure made of natural silicon-crystalline sand, delivering efficient broadband double-sided sound absorption and excellent sound wave diffusion performance. Different from traditional products relying on Sound Absorbing Cotton, this inorganic absorber maintains stable and long-lasting acoustic effects without performance attenuation. It boasts Class A fire resistance, formaldehyde-free environmental protection, superior moisture resistance and sturdy structure, requiring minimal daily maintenance for long-term use. As a high-performance suspended Sound Absorbing Panel, it adopts flexible hoisting installation that saves wall space and adapts to various large indoor layouts. Equipped with matched Shock Absorbing Board at mounting points, it effectiv…
