Acoustic resonance scattering has received a systematic theoretical description by the so-called “Resonance Scattering Theory” (RST) [L. Flax, L. R. Dragonette, and H. Überall, J. Acoust. Soc. Am. 63 (1978) 723-731]. The often prominent resonant vibrations of elastic objects, as excited by incident acoustic waves, have been subject to numerous experimental studies since about 1980, often employing an experimental method termed MIIR [G. Maze and J. Ripoche, Rev. Phys. Appl. 18 (1983) 319-326]. Recent experimental results are described here, together with their theoretical analysis.
