High-Efficiency Sound Absorption, Optimizing Acoustic Environment
The core function of upholstered acoustic panels is to absorb sound waves, reducing echo and reverberation. Their interior is typically filled with porous sound-absorbing materials (such as polyester fiber cotton, glass wool, rock wool, etc.). When sound waves enter the material, air molecules vibrate and create friction within the pores, converting sound energy into heat, thereby achieving the sound absorption effect. Depending on the material density and thickness, the sound absorption coefficient (NRC) can reach 0.8-1.0 (the higher the NRC value, the stronger the sound absorption). They are particularly effective at absorbing mid-to-high frequency sounds (such as human voices and musical instruments), making them suitable for conference rooms, recording studios, cinemas, schools, and other settings where clear speech or music presentation is required.
Strong Decorative Appeal, Adaptable to Diverse Spaces
The outer layer of upholstered acoustic panels is covered with flexible fabrics, such as textiles (polyester fiber, cotton-linen, etc.), leather (natural or artificial), or PVC, with a wide variety of colors, textures, and patterns to match modern minimalist, industrial, classical, and other decoration styles. Additionally, fabric surfaces can be custom-printed with patterns or logos to meet branding or personalized design needs. Some high-end products also use flame-retardant, stain-resistant, and antibacterial fabrics, combining aesthetics with practicality.
Safe and Environmentally Friendly, Compliant with Industry Standards
Upholstered acoustic panels must meet strict environmental and safety standards. Environmentally, the core sound-absorbing materials must pass national mandatory certifications (such as China Environmental Label Certification), and formaldehyde emissions must be below the E1 standard (≤0.124 mg/m³) to ensure indoor air quality. Safety-wise, the fabric must have flame-retardant properties (such as B1 level), and the core material must pass fire tests (such as GB8624-2012 standard) to prevent fire spread. Moreover, some products also pass mold and moisture resistance tests, making them suitable for damp environments (such as basements and bathrooms).
Easy Installation, Low Maintenance Costs
Upholstered acoustic panels usually feature a modular design, commonly in sizes of 600mm × 600mm, 1200mm × 600mm, or custom dimensions. Installation is done via clips, adhesive, or mounting on a keel on walls or ceilings, requiring no complex tools, with a short construction period. For maintenance, the fabric surface can be cleaned with a vacuum cleaner or wet cloth, and the sound-absorbing material is not prone to aging, with a lifespan of over 10 years, making long-term costs lower than traditional acoustic materials (such as mineral wool boards).
Multi-Functionality, Meeting Special Needs
Some upholstered acoustic panels also have additional functions: for example, built-in soundproof felt can enhance noise insulation (suitable for KTV, computer rooms, and other environments needing to block external noise); adding an elastic base can improve impact resistance (suitable for children's activity areas); using breathable fabric can regulate indoor humidity (suitable for museums, archives, and other places sensitive to temperature and humidity).
