[Object] To provide an adaptive array control method, device, and program, and an adaptive array processing method, device, and program, capable of performing accurate coefficient update control independent of frequency characteristics and incoming directions of signals. [Achieving Means] The present invention is characterized as to array-process signals received from a plurality of pairs of sensors having a plurality of different sensor intervals, and using the array processing result, estimate interference power accurately. More specifically, the present invention includes a multiple blocking matrix circuit 320 which processes signals receiving from sensors having a plurality of different intervals, and an accurate coefficient update control is performed based on the output array-processed signal. Thereby, deterioration of output signals and breathing noises are reduced, and high-quality array processing can be performed.
