Estimation of parametric sound field controlled by source amplitudes and phases using numerical simulation
2012 (English)Conference paper (Other academic) Published
The purpose of this study is to investigate the effects of sound source conditions on the properties of length-limited parametric sound beam. Using numerical simulations, we evaluated the beam profiles of length-limited parametric sound varying the amplitudes and initial phases of sound sources. Numerical experiments indicated that, for the deviation of±10% from the optimal conditions, the amplitude deviation more affects the beam profiles than the phase deviations.
