The Properties of Water-Filled Tubes for Impedance and Speed of Sound Measurements (Die Eigenschaften Wassergefuellter Rohre fuer Widerstands- und Schallgeschwindig-keitsmessungen),

Abstract

After a description of water-filled tubes for various acoustic measurements, the lowering of sound velocity for low frequencies by the resilient tube wall and the dispersion at higher frequencies is dealt with. Disturbances of sound propagation in the water are caused only by free vibrations of the tube, the excitation of which is diminished by filters for structure-borne sound. The natural frequencies of various kinds and orders of free tube vibrations not yet described in the literature are given.
