Abstract
It is well known that noise emitted from piping in process plant is deeply affected by vibration. However, it is very difficult that noise levels are estimated based on vibration levels at piping or cylindrical supports. This paper describes a experimental investigation of relation between radiated noise and vibration using method of EEMUA No.142,and study for influence on piping structure of generated noise inside piping using sound-structure interaction analysis which is the focus of major oil companies in recent years.
