Abstract

In this paper, we applied the Direct Adaptive Algorithm (DAA) to active noise control (ANC) of low-frequency impact noise with a dominance at the 63 Hz to 125 Hz. DAA can carry on the adaptive feedforward control without identifying the acoustical property of a secondary path. It can also reduce the noise even if the control position moves. We develope an impact noise generator for the experiment. A control effect is rated with difference of sound exposure level. From the simulations, an enough validity of control is shown after ten times of impact. The possibility of using ANC against the impact noise is shown from both the simulations and experiments.
