Nonlinear Distortion in the Propagation of Intense Acoustic Noise,
Abstract
As sound pressure increases to 'finite' levels, nonlinear effects usually ignored in acoustics problems become increasingly important. In this paper plane waves propagating through a pipe are considered. In the first section the distortion of a wave that is sinusoidal at the source is treated. In the second section the source signal is a pulse band-limited (500 to 3500 Hz) random noise. In both cases theoretical results are compared with experimental measurements. Extension of the analysis to the more practical case of outdoor propagation is indicated.
