Research on the Acoustic Insert Loss in Water Filled Pipes

Abstract:

Water filled pipe as an experimental model of the sea pipeline on ships, the study has very important significance of the sound propagation characteristics. In this paper, eigenfunctions of pipeline interior sound field are theoretically calculated at first. And through the Matlab software simulation calculation, the cutoff frequency is shown. And then, the water filled pipe acoustic insertion loss is given by the experimental study. Through the research, we validate the cutoff frequency calculation, and gives the insertion loss of pipelines.
