Abstract
Anti-Sound is simply a catchy name given to a sound field deliberately created to interfere destructively with an undesirable sound, the linear strictly anti-phase superposition of the two fields amounting everywhere to zero disturbance. Silence might then be regarded as the superposition of sound and anti-sound, but that view appeals only when silence is maintained by opposing sources, individually active but collectively silent, a silence that is easily broken by obstructing the field of either the primary or the interfering source.
