Abstract
The propagation of longitudinal acoustic waves in weakly compressibleelastic media permeated with air bubbles is investigated on the basisof the radial pulsation equation of a single bubble. The multiplescattering of waves in such media is rigorously described by using aself-consistent approach. Theoretical results show that there existsstrong acoustic localization in a range of frequency slightly above thebubble resonance frequency, even for a very small volume fraction ofbubbles. Further study reveals that the localization is in factattributed to collection behaviour of bubbles, allowing for anefficient cancellation of propagating waves. This is essentiallyconsistent with the known conclusions recently drawn for bubbly liquidby Kou et al. [2003 Appl. Phys. Lett. 83 4247]
