Abstract

The invention discloses a steel structure factory building sound insulation and noise reduction wall based on modularized composite vibration isolation, relates to the technical field of factory building construction, and aims to solve the problem that equipment vibration in a factory building is easily transmitted to a sound insulation wall body through a steel structure, so that the overall sound insulation capacity of the sound insulation wall board is reduced. The sound insulation module is formed by sequentially compounding an impedance layer facing a sound source side, a damping constraint layer of a core and a mass layer facing the back of the sound source side, wherein the impedance layer is a metal microperforated plate. According to the invention, the multilayer composite design combines the impedance matching, damping dissipation and mass sound insulation principles, so that the sound insulation module has excellent noise reduction capability in a wide frequency range, and meanwhile, the selection of materials gives consideration to durability and practicality, thereby being applicable to the noise control requirements of various industrial plants.
