Which of these sets lists materials specifically identified as key modern components for managing sound *within* a space (absorption)?
Answer
Fiberglass, Mineral Wool, and Foam.
The modern toolkit separates materials based on function. Materials designed for absorption are porous, allowing sound waves to enter and dissipate energy through friction as heat. Fiberglass, often formed into dense boards, is a highly effective core for acoustic panels. Mineral wool functions similarly, offering excellent absorption capabilities. Engineered, open-cell foams are also used extensively, especially in sensitive environments like recording studios, where controlling reverberation and flutter echo internally is the primary goal.
