Prediction of audio sound generated by parametric speaker

Abstract (in Japanese) (See Japanese page) 
(in English) When a parametric loudspeaker self-demodulates audio signals, nonlinear
distortions such as higher harmonics are generated inherently and
simultaneously.
The final goal of this study is to realize a simple electric system for
reducting such distortions as much as possible using a feedback circuit
that includes a waveform predictor of parametric sounds in real time.
To this end, the present report simulates the demodulated process of
parametric sounds based on Merklinger's model equation.
It is successfully demonstrated that two typical audio signals that are
composed of sinusoidal waves are precisely predicted by the present simulation
procedure.
