A self-checkout system1includes a console2for interacting with a user, in the form of consumer3. This consumer3is located within a spatially defined control zone4during such interaction. An interface5is responsive to console2for receiving a first signal6indicative of an audible representation7. A processor8is responsive to the signal6for selectively defining a second signal, in the form of ultrasonic transmission9. An output, in the form of an ultrasonic transducer10, is responsive to processor8for propagating transmission9to provide only in the control zone4audible representation7.
