More Information
Summary:A signal processing device is provided with: a means for receiving an input acoustic signal; a means for modulating the amplitude of the received input acoustic signal to generate an output acoustic signal having a change in amplitude in accordance with the frequency of the gamma wave, the rising and falling of the envelope of the amplitude waveform being asymmetrical; and a means for outputting the generated output acoustic signal. 信号处理装置具备：受理输入音响信号的单元；通过对所受理的输入音响信号进行振幅调制来生成具有与伽马波的频率对应的振幅的变化、且振幅波形的包络线的上升与下降呈非对称的输出音响信号的单元；以及输出所生成的输出音响信号的单元。
