Ultrasonic velocities and densities have been measured in ternary mixtures containing copper soap-urea complexes derived from groundnut and sesame oils in a 20$\%$ and a 40$\%$ methanol-benzene mixture. From these values, the specific acoustic impedance $Z$, adiabatic compressibility $\beta$, intermolecular free length $L_{\rm f}$, apparent molar compressibility $\phi_{k}$, molar sound velocity $R$, primary solvation number $S_{n}$ have been calculated. The results have been analyzed in terms of Masson's equation. The results have been explained on the basis of intermolecular interactions, and the effect of the polarity of the solvent molecules and the concentration of solute molecules were accessed on various acoustic parameters. Our results also suggest that the behavior of soap complex in benzene dominated environment and methanol dominated environment is quite different as they occupy different positions in palisade layers of soap complexes agglomerations.
