Anti-sound
From MediaWiki
Anti-sound is a sound wave used to cancel or nullify other sound(s). It is also known as white noise.
In the real world anti-sound devices are used in areas where undesirable sounds originate such as traffic.
The concept was introduced in Arthur C. Clarke's 1957 short story, "Silence Please". Clarke intended it as a humorously improbable device - with dire consequences for the inventor.
The citizens of Eurhythma used anti-sound to cancel out the destructive melody stolen from them by Soundwave (Carnage in C-Minor).
