A technique is described for operating a gaming machine adapted to receive a wager on a game of chance. In at least one embodiment, the gaming machine may be adapted to dynamically change its volume. In one implementation, the gaming machine may include a first movable display which may be used to dynamically and/or automatically change the volume of the gaming machine. For example, the first movable display may be automatically moved to a first position to thereby establish a first volume of the gaming machine. The first movable display may also be automatically moved to a second position to thereby establish a second volume of the gaming machine.
