✦ Synopsis
show that the part of bending or elbow is excited by the impulsive pressure of exhaust gas and generates a vibration, and the generated vibration is spread over the manifold and radiates high frequency noise at about same time. We also study the noise reduction method for the exiting part, transmission part and radiation part.
