Abstract
A method is described which applies Acoustic Spectrometry to characterize both the particle size distribution and mechanical properties of the soft particles in concentrated dispersed systems. It is shown that compressibility of the soft particles can be calculated from the measured sound speed using well-known Wood expression. The value of the thermal expansion coefficient can be calculated from the measured attenuation spectra either for known particle size or together with particle size as adjustable parameter.
