Comparative Study on Radiated Noise Estimation Error with Sound Pressure and the Pressure Variation

Abstract:

A new method, which combines the measurement and the estimation of the radiated noise variation, is proposed in this paper to predict the real-time radiated sound pressure. The estimation errors of the pressure variation are calculated and compared with the pressure estimation errors, using the Boundary Element Method(BEM). The comparison results show that the errors of the pressure variation estimation method are smaller than direct sound pressure estimation at the eigenfrequencies and most frequencies. The method can be used to decrease the real-teime radiated sound pressure estimation error.
