A Study on Noise and Vibration Characteristics of Pipe Structures

The paper presents noise and vibration characteristics of three kinds of pipe materials (PVC pipe, cast-iron pipe and newly developed pp pipe). In order to measure structure bone noise, impact force using small balls was applied to earth pipe. It was confirmed that structure bone noise can be reduced by more large damping materials. Also, transmission loss of pipes depending on the frequency ranges was investigated by using sound source through speakers.
