Isolation booth

From Wikipedia, the free encyclopedia

An isolation booth is a device used to prevent a person or people from seeing or hearing certain events. On game shows, the isolation booth might be used to prevent contestants from hearing the other player's answers (such as on Twenty One, Family Feud, Win Ben Stein's Money, and the CBS version of Double Dare), from hearing the audience (The $64,000 Question, The $1,000,000 Chance of a Lifetime), from seeing moves or plays made by a player (Whew!) or sometimes for comedic effect only (Idiot Savants).

Isolation booths are also frequently used in audio recordings, with non-reflective walls, that eliminate potential reverberations.
