Third party's conversation can easily ill influence on one's work efficiency. A sound masking method can be used for masking against the conversation sound on such a situation. This method is effective in open space such as office or living room. However, a noise level after masking inevitably be increased with conventional masking approach. In this paper, an approach aiming to decrease noise level after masking with active noise control is investigated. Since the virtual microphone method is used, no microphones are necessary in this approach. Recognition rates, the masking effectiveness, are evaluated with simulations and experiments at several points.
