Abstract The acoustic nonlinearity parameter B/A of a liquid containing microbubbles, sonicated dextrose albumin, has been measured by using second harmonic insert-substitution method. Results show that the value of nonlinearity parameter B/A for a bubbly liquid is significant and it obviously increases with increase of bubble number density. The high nonlinearity of the bubbly liquid is mainly dependent on the microbubble nonlinear oscillation.
