Original Abstract

This paper discusses the parametric transmission of sound through an amplitudemodulated ultrasonic wave, using automatic demodulation in a non-linear environment. Methods for the processing of the transmitted signal are presented; these techniques employ modified amplitude modulation to suppress the environmental effects, which otherwise distort the signal. Within our research, we fabricated a parametric speaker consisting of 50 ultrasonic acoustic transducers with the resonant frequency of 40 kHz. The functionality of the acoustic source was verified via measurement of the total harmonic distortion (THD).
