Nonlinear acoustics (NLA) is a branch of physics and acoustics dealing with sound waves of sufficiently large amplitudes. Large amplitudes require using full systems of governing equations of fluid dynamics (for sound waves in liquids and gases) and elasticity (for sound waves in solids). These equations are generally nonlinear, and their traditional linearization is no longer possible. The s… WebAs noted above, acoustic waves in the atmosphere can be viewed as small disturbances on an ambient background fluid, just as water waves are seen as disturbances on a calm surface. For the extremely small pressure perturbations typical of sound, the equations of fluid dynamics can be linearized to arrive at the ‘acoustic wave equation’, which is the … timothy dills
