A noise reduction device that reduces noise (N e ) in a sound reception location different from a sound collection location, the noise reduction device comprising: a first input terminal that inputs a noise reference signal correlated with the noise (N e ); a standard signal generator that generates a standard signal having a frequency specified based on the input noise reference signal; an adaptive filter unit that generates an output signal (Out) to be used to output a cancellation sound (C e ∗Out) for reducing the noise (N e ), by applying a filter coefficient to the generated standard signal; an output terminal that outputs the generated output signal (Out); a first corrector that generates a corrected standard signal by correcting the generated standard signal based on a transfer characteristic (C e ) of a transmission route of the output signal (Out); a second input terminal that inputs an error signal based on a residual sound occurring in the sound collection location different from the sound reception location due to interference between the cancellation sound (C e ∗Out) and the noise (N e ) characterized by a second corrector that generates a correction signal by correcting the output signal (Out) or the standard signal by a predetermined parameter and adds the generated correction signal to the error signal, to generate a corrected error signal approximating the error signal to an error signal indicating a residual sound occurring in the sound reception location different from the sound collection location; and a filter coefficient update unit that sequentially updates the filter coefficient based on the generated corrected error signal and the generated corrected standard signal. a first input terminal that inputs a noise reference signal correlated with the noise (N e ); a standard signal generator that generates a standard signal having a frequency specified based on the input noise reference signal; an adaptive filter unit that generates an output signal (Out) to be used to output a cancellation sound (C e ∗Out) for reducing the noise (N e ), by applying a filter coefficient to the generated standard signal; an output terminal that outputs the generated output signal (Out); a first corrector that generates a corrected standard signal by correcting the generated standard signal based on a transfer characteristic (C e ) of a transmission route of the output signal (Out); a second input terminal that inputs an error signal based on a residual sound occurring in the sound collection location different from the sound reception location due to interference between the cancellation sound (C e ∗Out) and the noise (N e ) characterized by a second corrector that generates a correction signal by correcting the output signal (Out) or the standard signal by a predetermined parameter and adds the generated correction signal to the error signal, to generate a corrected error signal approximating the error signal to an error signal indicating a residual sound occurring in the sound reception location different from the sound collection location; and a filter coefficient update unit that sequentially updates the filter coefficient based on the generated corrected error signal and the generated corrected standard signal. <EOS>
