The invention relates to a method for carrying out low-
frequency noise environmental governance by utilizing a super
sound absorber. The method comprises the following steps of: 1, measuring a
noise frequency of a low-
frequency noise source; 2, determining a height of the super
sound absorber according to a space distance between a cover of the low-
frequency noise source and the low-frequency
noise source; 3, manufacturing super
sound absorber models in different specifications; 4, respectively putting a first detection group and a second detection group into a B&K type 4206
impedance tube tocarry out
sound reduction index test; 5, carrying out theoretical
simulation on
resonant cavity sound absorption by utilizing COMSOL
software until theoretical data fit by the COMSOL
software is basically consistent with experimental data in the step 4; 6, carrying out extended
simulation on the
resonant cavity sound absorption by adoption of a
control variable method by utilizing the COMSOL
software and finally determining a film thickness and a
diameter; and 7, manufacturing a plurality of super sound absorbers and fixed the bottoms of the super sound absorbers on the inner wall of the coverof the low-frequency
noise source. According to the method, specificity absorption at specific frequencies is realized via minimum space and material and lowest cost.
