摘要
In the noise reduction device, the sound receiver receives a noise signal acquired from the microphone. The sound source input unit receives an input of a sound source signal from a sound source. The sound adjuster changes the intensity of the sound source signal relative to the intensity of the noise signal. The control sound generator generates a control sound signal that reduces the noise signal. The control unit controls the change of the intensity of the sound source signal and the generation of the control sound signal. The sound output outputs the control sound signal to the speaker. The sound output outputs to the speaker the sound source signal at the intensity changed by the sound adjuster.
