Loudspeaker beamformers such as commercial sound bars can be used to produce narrow beams of sound that mainly reach the listener on distinct reflection paths or the direct path in the room. What happens if such variable directivity loudspeakers create two simultaneous beams of sounds with the same signal, each of which pointing to another acoustic path in the room? What is the resulting perceived direction of such a phantom source, and how do changes of time and level differences in the signal pair affect the result? This paper investigates these questions by a listening experiment that employs an auralized 3rd order source.
