Ultrasonic velocity and density are measured in the mixture of cholesterol in ethanol and 1-propanol solution at different concentration to study the thermodynamic properties. Acoustical parameters like adiabatic compressibility, intermolecular free length, acoustic impedance and surface tension are calculated using the ultrasonic velocity and density. These data are particularly discussed with respect to the concentration of cholesterol. The variation of ultrasonic velocity shows a dip at higher concentration of cholesterol. These properties are used to illustrate the nature of interactions between component molecules.
