It is the phenomenon that exists in empty elevators, darkened parks, odd Bobst nooks and penultimate subway stops: quiet. In a city where noise penetrates every wall and loudness guarantees instantaneous, hard-won attention, quiet is an endangered species with little advocacy over its disappearance. After all, New York is notorious for its nonstop vivacity and pizzazz, not its quiet. This issue is not about celebrating silence, nor is it about condemning loudness — it is about how to escape the constant sensory harassment, how to enjoy quiet activities and where to appreciate the potential softness of sounds. Lower the volume. Aerate sound with silence. You may not always need so much noise in your life.
