NOISE REDUCTION DEVICE, MOBILE BODY DEVICE, AND NOISE REDUCTION METHOD

A noise reduction device includes a second corrector that generates a correction signal by correcting an output signal or a standard signal by a predetermined parameter and adds the generated correction signal to an error signal, to generate a corrected error signal approximating the error signal to...

Beschreibung
Zusammenfassung:	A noise reduction device includes a second corrector that generates a correction signal by correcting an output signal or a standard signal by a predetermined parameter and adds the generated correction signal to an error signal, to generate a corrected error signal approximating the error signal to an error signal indicating a residual sound occurring in a sound reception location.
