Abstract
Acoustic noise from the various facilities makes man unpleasant and let researchers find the way for reducing it on environmental point of view. Special way to reduce the acoustic noise had suggested by the concept of Active Silencer. But, it has propagation delay time accumulated during the signal passage and howling effect. This paper suggestes a way to anhilate howling effects, and reduces the total delay time drasticaly by attaching microphone to the speaker. This paper will show how it works by some materials.
