In this embodiment, the number of the first noise reduction modules 10 is three, the three first noise reduction modules 10 are sequentially fixed and inserted in the first mounting frame 2 from bottom to top, and the upper end surface of the uppermost first noise reduction module 10 is flush with the upper end surface of the first mounting frame 2.

[0030] See Figures 1 to 4The first noise reduction module 10 comprises a punched mesh plate 3, a first mounting groove 1, wave cotton 5, a foamed plastic plate 6 and rock wool 7. The wave cotton 5, the foamed plastic plate 6 and the rock wool 7 are sequentially arranged in the first mounting groove 1 from front to back, and the punched mesh plate 3 is detachably arranged on one side of the first mounting groove 1. Specifically, the first mounting groove 1 is provided with a third fixed plate 11 at the upper end and the lower end, and the punched mesh plate 3 is arranged on the third fixed plate 11. The punched mesh plate 3 and the third fixed plate 11 are connected by bolts. The wave surface of the wave cotton 5 faces the punched mesh plate 3. The wave cotton 5 forms a micro air flow channel inside, which is beneficial to the flow of air in the material. This design not only helps to expand the range of energy dispersion, but also optimizes the air circulation inside the enclosure to a certain extent, reduces the reflection and resonance of sound waves inside the enclosure. The design of the wave shape increases the surface area of the wave cotton, which can better absorb the sound waves entering the enclosure through the punched mesh plate. The design of the wave surface of the wave cotton 5 facing the punched mesh plate 3 can significantly enhance the sound absorption capacity of the enclosure body 100, optimize the sound wave path and improve the structural stability in the noise reduction enclosure for building construction. The punched mesh plate 3 is provided with a plurality of through holes 31, and the diameter of the through holes 31 is 1-3 cm, preferably 1-1.5 cm. The first mounting groove 1 is provided with openings 12 at the left and right ends, which facilitates the disassembly and assembly of the wave cotton 5, the foamed plastic plate 6 and the rock wool 7. The punched mesh plate 3 allows part of the air to circulate while blocking large particles from entering the enclosure. The through holes 31 on the surface of the punched mesh plate 3 can also reduce the reflection of sound waves to a certain extent, providing better sound absorption conditions for subsequent materials. The wave cotton 5 helps the sound waves to reflect and consume energy multiple times inside the material, thereby improving the sound absorption effect. The wave cotton, as the main sound absorption material, can effectively absorb medium and high frequency sound waves. The foamed plastic plate 6 has good sound insulation performance and can further block and weaken the propagation of sound waves. The rock wool 7 effectively blocks the propagation of low frequency sound waves due to its high density and good sound insulation performance, thereby improving the noise reduction effect of the overall enclosure.
