Abstract : We have previously pointed out that using linear Doppler effect analysis to evaluate scattering by a vibrating surface produces inaccurate results in acoustics, except under highly specialized conditions. Our objections are based on the fact that medium nonlinearities, and nonlinearities in the fundamental acoustical equations, produce much stronger effects than those predicted on the basis of linear acoustical theory. In the subject paper, it is suggested that our objections do not apply to the case.
