Active noise control (ANC) has been known as a way to decrease low frequency noise in a duct. So far, we have developed an active noise control system in a duct using analog circuits. However the noise canceling effect of this analog ANC was not so high because of time lag between noise passing the duct and signal passing the circuit. To increase the noise canceling effect, in this study, we added an all-pass filter circuit to the analog ANC circuit in order to delay signal in the circuit. As a result, we confirmed improvement of the noise canceling effect of the analog ANC circuit by addition of the all-pass filter. |
