Sound in theatre goes beyond finding the right sound effects for a production. Sound engages audiences: it helps deliver information, it increases the production value, it evokes emotional responses, it emphasises what's on the stage. It can be used to establish the time or location of a performance, or to create and enhance mood and atmosphere. Time and location are the 'when' and 'where' of a production.
