| Research Abstract |
This paper presents the improvement of sound attenuation performance of active noise barrier. At first, the proposed method is able to switch appropriately for estimated incident direction of noise between filters identified in preliminarily to estimate signal in control location. This method is able to maintainthe sound attenuation at a control location in change of incident direction of noise. In addition, As a result of computer simulation, combining feedforward control with feedback control expands control area
