Taking about viscous resistance and surface tension, acoustic propagation in bubbleliquid medium are studied based on pressure and radial vibration velocity in bubble wall.By using Spheric Bessel and Hankel function,the acoustic parameters are investigated; the numerical results of acoustic velocity and coefficient of attenuation are obtained.The results show that acoustic velocity will decrease and coefficient of attenuation increase following the changes of bubble volume fraction.The influence of bubble on acoustic velocity is obvious in the condition of low frequency;but energy loss is obvious in the condition of high frequency.
