Background
Since the rapid development of the modern industry, the transportation industry and other industries, the problems of environmental pollution, noise pollution and the like become more and more serious, and with the technological progress and social development, people pay more attention to the harm brought by the pollution.
Although the wall of a building and the like can prevent partial noise from entering a room, partial low-frequency noise with longer wavelength cannot be prevented, and it is the low-frequency noise which affects normal learning, life and work of people. In the past, sound absorption cotton with porous sound absorption performance is mostly adopted for noise treatment measures which are generated indoors and indoors, but the common sound absorption cotton has the limitation of the noise reduction effect of common porous materials. The sound absorption effect of the porous material mainly depends on the consumption of sound waves in the propagation process of the material, so that the medium-low frequency sound absorption performance is poor and the sound absorption effect depends on the thickness of the material. The material thickness must be increased to achieve good sound absorption. However, some use environments have strict requirements on the thickness of the material, so that the sound absorption performance of the common fiber porous material cannot be normally exerted. Based on the excellence of the high-frequency sound absorption performance of the porous sound absorption material, the improvement of the porous sound absorption material to improve the low-frequency sound absorption performance and simultaneously have the broadband sound absorption effect under the condition of basically unchanged weight and thickness is always a technical problem in the field, and the improvement cannot be realized only by changing the self structural parameters of the porous material at present.
