Selecting the correct material is vital for performance. Polyester Fiber (PET) panels are eco-friendly, durable, and ideal for offices or schools due to their impact resistance. Acoustic Foam is cost-effective for temporary setups or podcasting but has lower fire resistance. For high-end architectural projects, Fabric-Wrapped Fiberglass offers the highest Noise Reduction Coefficient (NRC), while Grooved Wooden Timber panels provide a balance of sound diffusion and aesthetic luxury for auditoriums.
