Abstract
Telephone voice is annoying in public spaces like trains and cafés. The speaking voice was tried to be attenuated by using an active noise control technique. It is called `Voice Shutter´. Two types of voice shutter, which are open type and closed type, are proposed in this paper. A closed type voice shutter controlled by a feed forward method was manufactured and tested. As the results, the voice shutter was proved to be feasible, although it was too large for practical use, in this stage.
