How do composite materials reduce noise in outdoor chairs during use?

Composite materials are increasingly used in outdoor furniture, particularly chairs, due to their exceptional noise-reducing properties. These materials combine two or more substances to create a product with superior performance characteristics, including sound absorption and vibration damping.

One primary way composites reduce noise is through their layered structure, which disrupts sound waves. The fibers and resins in composites absorb vibrations, preventing them from transferring into audible noise. Additionally, their high internal friction dissipates energy, further minimizing sound transmission.

Unlike traditional materials like metal or wood, composites are less prone to creaking or rattling, ensuring a quieter seating experience. Their durability also means noise reduction remains effective over time, even with frequent use. By integrating composites, outdoor chairs achieve both functionality and enhanced acoustic comfort.
