The method of audio digital watermark based on dither modulation is dedicated to the problem which a watermark directly inserted into low frequence part made out sensitive noise,being subsection for audio signal by audio mesk effect,taking low frequence part of discrete wavelet transform,and inserting into scrambling watermark by dither modulation.

Study on relationship between noise sensitivity and mental health status;

Adaptive blind watermarking based on chaotic sequence and noise sensitivity;
