Abstract

We have studied the effect of an external acoustic wave on bubble displacements inside an aqueous foam. The signature of the acoustic-induced bubble displacements is found using a multiple light scattering technique, and occurs as a modulation on the photon correlation curve. Measurements for various sound frequencies and amplitudes are compared to analytical and numerical simulations. These comparisons finally allow us to elucidate the non-trivial acoustic displacement profile inside the foam; in particular, we find that the acoustic wave creates a localized shear in the vicinity of the solid walls holding the foam. This study of how bubbles "dance" inside a foam as a response to sound turns out to provide new insights on both foam rheology at high frequencies, foam acoustics and sound transmission into a foam, and analysis of light scattering data in samples undergoing non-homogeneous deformations.
