Abstract:
A noise reduction device reduces noise at a second position by using a canceling sound emitted from a first position. The noise reduction device corrects, to a second transfer characteristic, a first transfer characteristic for when the first position and the second position are in a reference positional relationship, according to a signal indicating the positional relationship between the first position and the second position, and corrects a base signal based on the second transfer characteristic.

Claim (Index 4):
The noise reduction device according to  claim 3 , further comprising:\n a storage that holds information that associates a phase correction coefficient and the difference between the first distance and the second distance with each other, wherein the corrector identifies the phase correction coefficient corresponding to the difference between the first distance and the second distance by referring to the information stored in the storage, and changes the correction amount for the phase included in the first transfer characteristic by an amount obtained by multiplying the frequency of the base signal by the phase correction coefficient that has been identified.
