Employing a Rayleigh disc and a torsion vane placed in the same sound field, the particle velocity of the medium(air), from which the mean energy density E of the wave calculated, and the radiation pressure W on a circular plate were measured respectively. The values of the ratio W/E thus obtained for the various frequencies were compared with the theoretical values calculated by the present author. The experimental result pointed out that the radiation pressures by the waves of equal intensity very remarkably according to the frequency and the property of the sound field. The frequency range of this experiment was from 1 kc. to 12kc. and the diameter of the circular plate 3. 2cm.
