The influence of leakage noise on the noise drops efficiency of elevated structure noise barrier;

According building the tube rows experimental platform,the leakage acoustic wave in the superheater was studied in this paper.

Based on the assumption of Nelson and Morfey that there is a constant of proportionality between the fluctuating drag force and the steady state drag force acting on an in-duct element, a pressure-based technique is proposed for estimating the breakout noise due to the vibration of the duct wall caused by the interaction of the turbulent flow and the in-duct elements.

A finite element model for structure acoustic coupling analysis of the acoustic leakage problem in an automobile passenger compartment;

A so called "acoustic leakage boundary condition" is put forward for an elastic thin walled cavity containing a leakage conduit and introduced to set up an improving finite element model which can deal with the structure acoustic coupling analysis of the acoustic leakage problem in an automobile passenger compartment.
