Abstract

n this paper we present the experimental results which are concerned by the propagation of ultrasound waves through a granular medium. The acoustic excitation is realized with transducers and the analysis it made in time-frequency domain. The experiments realized show that the detected acoustic signals are very different according to the polarization of the acoustic excitation and detection. In the low-frequency domain the spectroscopy of the transmitted impulses gives rise to peaks the existence and the origin of which are discussed..
