• Measurements were made on the vibrational acceleration of a point on a plate and the sound pressure near the plate surface. Attention was given to the initial values of the above quantities, together with coincidence frequency and the waveform of impulsive force, and the following results were obtained. 1) There is a close relation between the hammer momentum (mv) and the initial value (A_0) of the acceleration or the sound pressure, as expressed by the empirical formula; A_0=K_2(mv)^K1. The physical meaning of these coefficients is considered. 2) The correspondence between vibrational acceleration and sound pressure is fairly complex and depends upon the mechanical properties and thickness of the plate. The coincidence effect was observed. 3) The waveform of the impulsive force was observed with different stiffnesses and with various velocities of the hammer.
