silence

it's also an idea. I want to make a space or maybe a room that either emit some wave to interference with the sound when the audience is talking, therefore although the audience is talking, but the people beside the talking one will hear nothing , which means that in this space, we can talk but there's no sound, I think it's very interesting that , in this society , we always can talk, but just like no one is hearing or couldn't hear us, therefore i have this idea.
