The mainstream materials and technical characteristics of artistic sound-absorbing panels revolve around the dual goals of acoustic efficiency and decorative performance, forming four core systems:

Polyester fiber material

Using recycled PET fibers as the matrix, after hot pressing and surface needle punching treatment, it has a high porosity structure, and the NRC sound absorption coefficient can reach 0.8-0.95, significantly absorbing mid to high frequency noise (500-4000Hz). The material is lightweight and flexible, supporting laser cutting, molding carving, and multi-color dyeing and finishing, and can achieve modular splicing forms such as hexagonal, honeycomb, and wave. The fire rating reaches B1 level, the environmental standards comply with E0/E1, there is no formaldehyde emission, suitable for indoor wall and ceiling decoration, and it is currently the highest market share of artistic sound-absorbing products.

Glass wool and fiberglass fabric materials

Using ultra-fine glass fiber as the core and covered with flame-retardant fabric or leather, it has high density and fine fibers, with a stable NRC value of 0.8-0.86. It has good absorption ability for low-frequency sound waves (125-500Hz) and is commonly used in low-frequency trap systems in recording studios and theaters. Has excellent moisture and mold resistance, suitable for spaces with high humidity. More than 200 textures and colors can be selected for the surface fabric, supporting seamless stretching process, visually similar to soft pack walls, and combining a sense of luxury and acoustic functionality.

Perforated aluminum plate and fiber cement board

Using aluminum alloy or fiber-reinforced cement substrate, geometric patterns, ink landscape or brand logos are formed on the surface through CNC precision perforation or laser engraving. The porosity and back cavity structure work synergistically, and the NRC value ranges from 0.7 to 0.83. It has A-level non combustible, weather resistant, corrosion-resistant, and UV resistant characteristics, suitable for building facades, public space curtain walls, and high pedestrian flow areas. Installation requires the use of sound-absorbing backboards to form a composite structure of "board cavity sound-absorbing cotton", achieving a dual expression of acoustics and art.

Mineral rock wool material

Made by melting and drawing natural basalt, the fibers are interwoven in three dimensions with uniform density. The NRC value is 0.75-0.85, and the sound absorption frequency band is wide, especially good at controlling the mid frequency range (250-2000Hz). The material is inorganic and non flammable, with a temperature resistance of over 600 ℃. It is commonly used in high-rise buildings, subway stations, studios, and other places with strict requirements for fire prevention and safety. The surface can be covered with non-woven fabric or sprayed with artistic coating, achieving a fusion of matte texture and customized patterns, combining functionality and modern aesthetics.

Each material has been certified by the national GB/T 20285-2006 "Classification of Hazardous Materials for Smoke Production Toxicity" and GB 8624-2012 "Classification of Combustion Performance of Building Materials and Products" to ensure safety and compliance. When choosing, it should be based on the comprehensive matching of spatial acoustic requirements, environmental humidity, fire rating, and design style, avoiding making decisions solely based on price or appearance.
