Fast evaluation of preprocessing methods of the parametric array loudspeaker

Fast evaluation of preprocessing methods of the parametric array loudspeaker
This paper introduces a fast evaluation method for the parametric array loudspeaker (PAL). The present practice uses repeated time-consuming measurements to acquire total harmonic distortion (THD) and sound pressure level (SPL) curves for every preprocessing method. Instead, the proposed method requires only the frequency response of an ultrasonic emitter, since measuring one frequency response is relatively easier than measurements of many preprocessing methods.

Abstract

This paper introduces a fast evaluation method for the parametric array loudspeaker (PAL). The present practice uses repeated time-consuming measurements to acquire total harmonic distortion (THD) and sound pressure level (SPL) curves for every preprocessing method. Instead, the proposed method requires only the frequency response of an ultrasonic emitter, since measuring one frequency response is relatively easier than measurements of many preprocessing methods.
