By using insert substitution method, the acoustical parameter of nonlinearity B/A have been determined for a series of liquid biological samples: porcine whole blood, bovine whole blood, milk and aqueous solutions of polyethylene glycol of various molecular weight. The values of B/A for solutions of PEG increase linearly with solute concentration and exhibit no evident dependence on solute molecular weight.
