13. One case considered in the study by Gee and Sparrow [6] dealt with the numerical propagation of an initially Gaussian, high-amplitude noise waveform. The statistics of the waveform itself do not change remarkably when nonlinearly propagated numerically. On the other hand, the statistics of the waveform time derivative change considerably as acoustic shocks form and a cracklelike quality of the noise is heard when the waveform is played back. The waveform is embedded as a hyperlink in the electronic version of [6].
