"What is silence? To most of us, it is found in temporary absence of sound: the quiet nights of sleep in suburban neighborhoods; the demi-beat before a pianist pounds the ivories; and the pause one takes after receiving bad news. In our world, silence is also abstract. It is the hush that blankets a city devastated by disaster. But silence – true silence – is neither poetic nor dramatic. For those who can no longer hear, it is constant and formless."
