The Debye temperature has been computed for four quaternary mixtures over the entire range of composition at 298.15K. We have applied three different approaches and evaluated the Debye temperature using experimental data of ultrasonic velocity and density. This paper aims to portray the comparison of all the three approaches applied on the four quaternary mixtures which is being done for the first time to the best of authors knowledge .A good agreement is observed among the values computed with all the three approaches.
