摘要

This work deals with the experimental study of the normal incidence absorption properties of several granular pastas, starchy foods and cereals as function of frequency in the range 50-1600 Hz. The influence of the size and the shape on the sound absorption was studied. The influence of these parameters on the resonance frequencies was also analysed.
