Notes
[edit]- In the real world, anti-sound devices (called active noise control speakers) 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.
