摘要:
A noise reduction audio reproducing method includes the steps of: generating, from an audio signal of collected and obtained noise, an audio signal for noise cancellation to cancel the noise by synthesizing the audio signal for noise cancellation and the noise in an acoustic manner, reproducing the audio signal for noise cancellation acoustically to synthesize this with the noise in an acoustic manner; emphasizing an audio component to be listened to, of collected audio; synthesizing an audio signal with the audio component to be listened to being emphasized, and the audio signal for noise cancellation to supply the synthesized signal thereof to an electro-acoustic converting unit; and controlling so as to supply an audio signal, with the audio component to be listened to having been emphasized, to a synthesizing unit, regarding only a section based on a control signal.
