Material composition and sound absorption principle of wood wool sound-absorbing panels

<p>Wood wool sound-absorbing panels are press-formed with long wood fibers and Portland cement, and the natural fiber texture is retained on the surface. The connected pores between fibers allow sound waves to enter and be converted into heat energy dissipation due to air friction. The NRC is usually between 0.7 and 0.9. </p><p>The cement base material gives the board Class A fire-proof and moisture-proof properties, making it suitable for humid and public spaces. The reserved cavity behind the board can further improve low-frequency absorption. Mushu provides wood wool sound-absorbing panels in various specifications. </p>
