The discussers note that the authors have presented results of variation of the noise level function of the size and the shape of the particles, and compare these results with observations made by others concerning the crushing occurrence as a function of the same parameters. Other researchers have reported that rounded sands are much more resistant to crushing than subangular to subrounded sands. It has also been observed that uniform soils crush more than graded soils. It has been noted that all other conditions being the same, coarse sands show more particle crushing than fine ones. The effect of particle size is masked by the coefficient of uniformity. This could modify the author's conclusions and permit a concordance between the influence of particle size and shape on the acoustic emissions and on the crushing behavior.
