Phase Control of Parametric Array Loudspeaker by Optimizing Sideband Weights
ICASSP 2022accepted
In this paper, we propose a method for controlling the directivity of parametric array loudspeakers (PAL) by optimizing the weights for the sideband signals. By setting the weights for the sideband signals in the single side-band (SSB) modulation to the optimum values, the directivity of the audible…
