Abstract:
The active noise control device detects noise, and delays a phase of a detected noise signal in a low frequency band. In a non-closed-type noise control device, since there occurs such a phenomenon that the phase of the noise signal advances in the low frequency band, the correction unit performs a correction to cancel the phase advance by delaying the phase. By outputting the noise reduction sound based on the phase-corrected noise signal, the noise is reduced.

Claim (Index 14):
A non-transitory computer-readable medium storing program executed by an active noise control device formed in a non-closed structure and performing a feedback control, the program causing the computer to function as:\n a noise detection unit configured to detect noise; a correction unit configured to delay a phase of a detected noise signal in a low frequency band; and an output unit configured to output a noise reduction sound which reduces the noise based on the corrected noise signal.
