• A study has been made on the effects of differences in input wave forms on densities obtained by compaction with vibration exciter. The input patterns included sinusoidal, triangular, saw-tooth, inverted saw-tooth, square, cyclic pulse and inverted cyclic pulse-waves.<BR>The highest density obtained for given acceleration was found to be with an input of saw-tooth wave at either 580 c/s or 800 c/s. As a general trend, the characteristics reported previously for the case of sinusoidal vibra-tion with respect to the influence of displacement and acceleration on the density obtained was found applicable to these other wave forms taken up this time.<BR>The relationship, between frequency and density obtained was however found to vary widely, and this together with the surprisingly strong effect provided by the polarity of waves on compaction efficacy attests to the complexity of the effects of differences in wave form.
