Abstract:
A noise reduction device includes a plurality of noise microphones, a noise controller, and a control speaker. The noise controller generates a control sound signal for reducing, at a center of control in a control space, noise detected by the noise microphones. The number of noise microphones disposed closer than a distance d from the center of control is less than the number disposed farther than distance d, when distance d is expressed as d=d0+t×v−λ/2, where λ is a wavelength corresponding to a control frequency f in the noise microphones, d0 is the distance from the center of control to the control speaker, t is the control delay time in the control speaker, and v is sound velocity. The noise microphones that are disposed farther than the distance d from the center of control are approximately equally spaced apart.

Claim (Index 4):
The noise reduction device according to  claim 1 , wherein\n the noise controller performs feedforward control.
