Deviation of experimental speeds of sound from the values predicted by different methods are sometimes interpreted in terms of molecular interactions. To this end, reference states must have clear physical meaning. In this work, two reference models were compared: a thermodynamically ideal solution and a model of additive passage times. Physical background of the differences was discussed. The role of an entropy changes in an medium compressed and decompressed by an acoustic wave was printed out. A hypothetical binary mixture of perfect gases served as an example of the discussed issue.
