We propose the audible sound enhancement based on the carrier with the periodic square-wave for a parametric loudspeaker. In this method, the sound pressure is enhanced by changing the carrier with the periodic sine-wave into the carrier with the periodic square-wave. From the results of experiments, we confirmed the effectiveness of the proposed method.
