A long steel pipe filled with water is set vertically on a water reservoir, and near the lower end of the pipe a source of sound is immersed so as to produce a purely sinusoidal wave in the pipe. The standing wave is produced in it between the wave radiated from the source and the wave reflected by the free surface at the upper end of the pipe. The axial distribution of intensity in the pipe was measured by a small Brocatube connected with a Rayleigh disc. The results of experiment show that the form of standing wave is quite different according to the hight of the water column in the pipe and is much distorted from a sinusoidal wave but the same pattern of wave is repeated every half wave-length. Owing to the elastic yielding of the wall of the pipe, the velocity of sound obtained from the experiment is smaller than that in free water, and is in close agreement with H. G. Green's calculation. The distortion of the wave is due to the existence of a Broca-tube in the sound field. The problem was solved theoretically and we foun a good coincidence between the theory and the experiment. |
