Composition
Sound-absorbing panels are typically made from materials that have porous surfaces or are fibrous in nature. These materials are designed to trap sound waves and reduce reverberation within a room. Common materials used include:
Acoustic Foam: Polyurethane foam or melamine foam that has an open-cell structure, allowing it to absorb sound waves effectively.
Mineral Wool: Comprising rock wool or fiberglass, it is dense and has a fibrous structure that can trap sound waves. Further, it often has fire-resistant properties, making it a safe choice for many environments.
Fabric Wrapped Panels: These are often composed of an absorbing material like acoustic foam or fiberglass wrapped in decorative fabric. The fabric allows some sound to pass through and be absorbed by the underlying material.
Wooden Panels: Perforated or slotted wooden panels can also serve as sound absorbers. The wood itself doesn't absorb much sound, but when designed with specific patterns, it allows sound to pass through to an absorbent material behind it.
: PET (polyethylene terephthalate) acoustic panels made from highly compressed polyester fibers can also be effective sound absorbers.
