Coalescence of nonlinear acoustic waves, with application to supersonic jet noise
… of coalescence that occurs when neighboring acoustic waveforms propagate in nearly the same direction and intersect to form a larger-amplitude waveform with increased nonlinear distortion. Coalescence is proposed as an explanation for the observation of steepened Mach waveforms and crackle …

Nonlinear Acoustic Waves Generated by Surface Disturbances and Their Effect on Lower Thermospheric Composition
<p>Recent nonlinear atmospheric models have provided important insight into acoustic waves generated by seismic events, which may steepen into shocks or saw-tooth trains while also dissipating strongly in the thermosphere. Although they have yielded results that agree with observations of …
