Summary
In a liquid containing gas bubbles the speed of sound is less than that in each phase separately. Using the equations of motion for a homogeneous liquid containing gas bubbles it is shown that the dominating attenuation of an infinitesimal disturbance is that due to the second viscosity. In the propagation of a finite compressive disturbance an expression for the time required for the disturbance to display shock characteristics is found in terms of the initial disturbance profile and the liquid-gas ratio.
