Acoustic Granulometry of Granular Avalanches: Laboratory Validation of the Size–Frequency Relationship
Granular flows generate intense acoustic emissions, yet the quantitative relationship between particle size and sound frequency remains poorly characterized for natural, irregular materials. This study investigates the inverse relationship between mean particle size and the spectral centroid of acoustic emissions under...
