| Abstract : | A b s t r a c t. Helmholtz integral is used to predict the acoustic pressure radiation near a vibrating-apple. Solution approaches are developed for the acoustic pressure of the spherical mode of an apple with a revolutionary shape. The distribution of the surface pressure as well as the pressure radiation from the apple surface are obtained. The influence of the apple properties and the transmission medium property on the distribution and magnitude of the pressure is analysed. |
