The sound absorption mechanism is that a large number of tiny communicated pores are formed in the material, sound waves can penetrate into the material along the pores, and the sound waves and the material generate friction action to convert sound energy into heat energy. The sound absorption characteristics of the porous sound absorbing material are such that the sound absorption coefficient increases gradually with increasing frequency, which means that low frequency absorption is not as good as high frequency absorption.

The aluminum honeycomb perforated sound-absorbing board is structurally characterized in that a perforated panel and a perforated back board are adopted, an aluminum honeycomb core is directly bonded with a high-quality adhesive to form an aluminum honeycomb sandwich structure, and a layer of sound-absorbing cloth is attached among the honeycomb core, the panel and the back board.

As an index from which a constituent material of the sound-absorbing panel is selected, a void ratio is often used. However, since the fiber-based sound absorbing material and the granular-based sound absorbing material have different methods of forming internal voids, the relationship between the porosity and the maximum sound absorption rate is not always fixed, and even if a porous sound absorbing material is selected using the porosity as an index, a sound absorbing panel exhibiting a good maximum sound absorption rate cannot always be obtained. In addition, even if the same fiber-based sound absorbing material is used, the sound absorbing rate may be different even if the porosity is the same due to the thickness and length of the fiber, or even if the same granular sound absorbing material is used, the sound absorbing rate may be different even if the porosity is the same due to the size of the inorganic particles formed or the method of adhering the binder. That is, even if the porosity is the same, the paths through which air flows are different depending on the components of the structure, and therefore, the relationship between the porosity and the sound absorption coefficient is not fixed.
