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 7):
The noise reduction device according to  claim 16 , wherein\n the processor detects a state change of a sound field in the space, and switches ON or OFF the output of the cancelation sound signal of at least one of the plurality of sound output devices, according to the change of state of the sound field.
