This study investigated the influence of the height loudspeaker positions and their signals on perceived overall sound quality. Two layers and a total of seventeen loudspeakers were used in a horizontal and height layer. Twelve participants were asked to subjectively rank and describe eight randomly presented configurations that consisted of four height loudspeakers. A set of inverse filters was generated and applied to remove the room’s acoustic influence and a new set of listeners were asked to evaluate sound quality. The experimental results indicate the significance of the height loudspeaker positioning for a perceived 3D sound field. These results show that the room’s acoustic influence affects desired perceptual characteristics of the sound field and influences subjective preferences.
