Abstract(in English)	Microphone array methods have been presented for sound acquisition in teleconference systems. However, the output signal of these methods often has frequency response degradation due to positional error between the target sound source and the focal point of the array. In this paper, we proposed the design of Filter-and-Sum array for near sound field to reduce the degradation of output signal. The computer simulations and experiments show that the proposed method is effective to reduce the degradation of output signal.
