TLDR
In this paper, it was shown that the velocity of sound cannot be a proper basis of comparison in any homologous series and the result of plotting the constant R against the molecular weight of members of a homology series leads to the equation R = αM + β, where α is a general constant and β a characteristic constant for any one homology.Abstract:
A study of the recently obtained data on the velocity of sound and density in liquids reveals a simple relation between these quantities namely the law, v⅓M/ρ = R where v is the velocity of sound in the liquid, M the molecular weight, ρ the density and R a constant independent of temperature. It is shown that the velocity of sound cannot be a proper basis of comparison in any homologous series. The result of plotting the constant R against the molecular weight of members of homologous series leads to the equation R = αM + β where α is a general constant and β a characteristic constant for any one homologous series. The difference in R for successive members of homologous series is a constant independent of the series and R is an additive function of the chemical structure. Values of R for hydrogen, carbon, oxygen, bromine, and chlorine are tabulated.read more

Chapter 14 – acoustic properties
TL;DR: In this article, the authors use acoustic measurements as a structural probe as the acoustic properties, especially sound absorption, are related to many structural factors, such as transition temperatures, morphology, cross-link density, etc.
