The advantage of sound-absorbing cotton is that it is easy to process during decoration. At the same time, sound-absorbing cotton is also moisture-proof and waterproof, and its breathability is better than other materials. However, sound-absorbing cotton also has its shortcomings. The sound-absorbing cotton has poor flame retardancy and cannot effectively block the spread of fire.

2. Wood wool sound-absorbing panels

Wood wool sound-absorbing panels are also very popular among indoor sound insulation materials. Wood wool sound-absorbing panels are mostly made of poplar wood fiber with natural texture. It satisfies people's pursuit of nature in urban life. The decoration of wood wool sound-absorbing panels is simple.

Some sound insulation materials based on plant fibers have very good sound insulation properties. For example, the wood wool sound-absorbing panels mentioned above.

2. The sound insulation effect of indoor sound-absorbing materials is mainly reflected in dispersing and absorbing sound to reduce the size of the noise. The most important of these is the absorption of sound. Therefore, there are more textures on the surface of sound-absorbing materials, which can hinder and disperse sound. The acoustic materials we usually refer to refer to our sound-absorbing materials.
