Abstract:
A noise reduction device is connectable to a plurality of sound acquisition devices and a plurality of control sound output devices for reducing noises in a given space where seats are arranged and a sound field can be formed. The device includes a sound receiver, a processor, a control sound transmitter. The sound receiver receives a sound signal from at least two of the plurality of sound acquisition devices. The processor detects a state change of the sound field, and generates a control sound signal for reducing noise with respect to the sound signal. The control sound transmitter outputs the control sound signal to each of control sound output devices. The processor acquires, for example, seat information for specifying the reclining state of a seat. The processor controls the generation of the control sound signal based on the change of state of the sound field including the seat information.

Claim (Index 14):
The noise reduction system according to  claim 10 , wherein\n the memory further stores, with respect to a partially reclined seat position control point at which noise is to be reduced: settings of each of the plural sound acquisition devices as either a noise sound acquisition device, an error sound acquisition device, or off; settings of each of the sound output devices as on or off, the partially reclined seat position control point being between the upright seat position control point and the reclined seat position control point; and the processor selects, based on a current position of the seat, the sound acquisition device and sound output device settings associated with either the upright seat position control point, the reclined seat position control point, or the partially reclined seat position stored in the memory; the plurality of control sound output devices includes one or more first control sound output devices disposed in an upper part of the given space, and one or more second control sound output devices disposed in a lower part of the given space; the plurality of sound output devices includes one or more first sound output devices disposed in the upper part of the given space, and one or more second sound output devices disposed in the lower part of the given space; when the processor selects the partially reclined seat position control point, the processor switches OFF the output of the cancelation sound signal to the one or more first control sound output devices, and switches ON the output of the cancelation sound signal to the one or more second control sound output devices; and when the processor selects the upright seat position control point, the processor switches ON the output of the cancelation sound signal to the one or more first control sound output devices, and switches OFF the output of the cancelation sound signal to the one or more second control sound output devices.
