| Abstract |
The Active Noise Cancelling(ANC) headphone is now becoming commercially available. But it reduces not only noise but also information signals such as speech or some signals including audible information in particular situation. In this paper, we propose an ANC headphone using adaptive beam-forming techniques which cancels signals except the headphone wearer's look direction signal. It enables workers working in noisy condition to talk with their coworkers. Computer simulation is performed to show the effectiveness of a proposed algorithm. |
