A series of bullet experiments were completed in a tank. The basic analyses are given for the pulse-form, relation between source strength and entrance angle θ, frequency spectrum and directivity of the impact noise produced by the entrance of the high-speed bodies into water. Since the splashes noise is a kind of hydrodynamic noise, the method of dimensional analysis is used to establish the dimensionless relations for estimation of the amplitude P_0 of impact noise and the time T_1 for the apperance of the first bubble pulse. The spread of sound impulse and horizontal directivity are also discussed for small entering angles.
