Abstract:
According to one embodiment, a noise reduction apparatus includes a first control sound source, a first current detection unit, a second control sound source, a second current detection unit, and an adjustment unit. The first control sound source generates a first control sound for reducing noise from a noise source. The first current detection unit detects a first current flowing from the first control sound source upon receiving the noise from the noise source. The second control sound source is provided at a position different from a position of the first control sound source and generates a second control sound for reducing the noise from the noise source. The second current detection unit detects a second current flowing from the second control sound source upon receiving the noise from the noise source. The adjustment unit adjusts the first control sound and the second control sound so as to make the first current and the second current satisfy a predetermined condition.

Claim (Index 1):
A noise reduction apparatus comprising:\n a first control sound source configured to generate a first control sound for reducing noise from a noise source; a first current detector configured to detect a first current flowing from the first control sound source upon receiving the noise from the noise source; a second control sound source provided at a position different from a position of the first control sound source and configured to generate a second control sound for reducing the noise from the noise source; a second current detector configured to detect a second current flowing from the second control sound source upon receiving the noise from the noise source; a processing circuit configured to adjust the first control sound and the second control sound so as to make the first current and the second current satisfy a predetermined condition; an acquisition device configured to generate a reference noise signal based on the noise from the noise source; a first control filter configured to adjust at least one of an amplitude and a phase of the reference noise signal and generate a first control signal supplied to the first control sound source; and a second control filter configured to adjust at least one of an amplitude and a phase of the reference noise signal and generate a second control signal supplied to the second control sound source, wherein the processing circuit adjusts the first control filter and the second control filter so as to make the first current and the second current satisfy the predetermined condition.
