| Abstract(in English) | An adaptive microphone array for noise reduction (AMNOR) minimizes a noise while limiting the degradation of a target sound to an acceptable level (called acceptable degradation: (AD)). When we set a large AD, noise can be greatly suppressed. However, the noise suppression function (directional characteristic and filter characteristic) of an AMNOR when the AD is changed has not been investigated. In this study, we examine the noise suppression function of an AMNOR, when the AD is changed from the minimum value to the maximum value. Then, it is shown that the noise suppression function of AMNOR changes with a change in the AD as follows; 1) delay and sum array, 2) subtraction array and compensation filter, 3) subtraction array and compensation except for zero frequency, 4) subtraction array and the Wiener filter. |
