AbstractAn experiment was carried out on the randomization process of a wake excited by random sound. The randomization is accelerated by random noise as well as by sinusoidal sound composed of seven distinct frequencies. The elementary-wave analysis method was used for clarifying the details of randomization mechanism. The so-called random number based on the analysis is a good indication of the progress of randomization.
