Analysis of the Influence of Vibro-Acoustic Coupling Effect on the Floor Sound Insulation

Abstract:

The difference between the theoretical calculation and the actual volume of sound insulation which appears in the actual engineering of water pump system always exceed the standard of noise in the residential areas. It is difficult to meet the requirement even when the quality of the project gets improved. In this paper, ,the acoustical mode is obtained by finite element method and the distribution of noise after coming through the floor is calculated in different frequency based on the theory of sound and vibration coupling effect . The result points out that the neglect of the vibro-acoustic coupling effect is the main reason of imprecise. The solution to the problem is put forward and the direction of the noise reduction measures in the future is pointed out .
