摘要： In a wireless communication apparatus, an ambient apparatus number measurement unit measures the number of wireless apparatuses existing around. A movement amount measurement unit detects acceleration at the time when its own apparatus moves and measures the movement amount of its own apparatus. An ambient sound analysis unit records ambient sounds and analyzes the recorded ambient sounds to generate ambient sound analysis information. A communication controller estimates surroundings of its own apparatus based on at least one of the number of the measured wireless apparatuses, the measured movement amount, and the ambient sound analysis information, and autonomously performs a communication control of its own apparatus according to the estimated surroundings.

摘要： As optimal candidate as a control signal (y*) for generating a control sound suppressing noise from a speaker is selected from among a plurality of control signal candidates (y1 to yn) by a selection function unit. For this selection, a residual noise estimation function unit receiving as input a residual noise signal (e) from an error microphone is introduced. The function unit first obtains an estimated value of a noise component using a first transfer characteristic simulating filter. Further, this noise component estimated value and filtered outputs from second transfer characteristic simulating filters are used to obtain residual noise estimated values for the control signal candidates (y1 to yn). Further, the single control signal candidate corresponding to the smallest of these residual noise estimated values is selected and used as the above control signal (y*).
