Abstract	Measurement of acoustic impedance requires both the measurement of ultrasonic velocity as well as density. The present work is an extension of our previous novel method reported and validated through a series of acoustic impedance studies carried out in a number of pure, binary and ternary liquid mixtures. To bypass the ambiguity of measurement of velocity and density independently, and to overcome the limitation of previously developed concurrent method for measurement of acoustic impedance, a new novel mathematical approach has been developed. Admittedly, in case of two liquids of approximately identical impedances, it is difficult to detect the variation using the proposed method. Consequently, the method requires some modification to study the small changes in acoustic impedance. In order to achieve the desired sensitivity, a novel mathematical approach has been developed and reported in this paper which overcomes the limitations of our previously developed concurrent method for the measurement of acoustic impedance. Present work analyses the factors that contribute to the sensitivity. Finally, a methodology has been suggested for achieving the maximum sensitivity. Several experiments were carried out using the present technique and results obtained clearly show higher sensitivity over the results obtained using previous technique. The modified method would be a useful tool for the researchers in a number of applications, such as the study of intermolecular interactions in liquids, adulteration estimation, finalization of process parameters, etc.
