Centrifugal glass wool has excellent sound absorption properties for high frequencies. The main factors affecting the sound absorption performance of centrifugal glass wool are thickness, density, and air flow resistance, among others. Density refers to the weight of the material per cubic meter. Air flow resistance is the ratio of air pressure and air velocity on both sides of the material per unit thickness. Air flow resistance is the most important factor affecting the sound absorption performance of centrifugal glass wool. Too low flow resistance indicates the material is sparse, making air vibrations easy to pass through, thus reducing sound absorption. Conversely, too high flow resistance suggests the material is dense, making it difficult for air vibrations to penetrate, also diminishing sound absorption. For centrifugal glass wool, there exists a flow resistance in its sound absorption performance.

Glass wool is a category of glass fiber, a man-made inorganic fiber. It is primarily made from natural ores such as quartz sand, limestone, and dolomite, along with some chemicals like soda ash and boric acid, melted into glass. In the molten state, it is blown or spun into fluffy fine fibers, with the fibers intersecting and intertwining in a three-dimensional manner, creating many small gaps. These gaps can be considered pores. Therefore, glass wool can be regarded as a porous material with excellent thermal insulation and sound absorption properties.
