The Effect of Head Movement on Perceived Listener Envelopment and Apparent Source Width
This study investigates the effect of head movement in the evaluation of LEV and ASW under 15 different concert hall conditions simulated over eight loudspeakers using Virtual Microphone Control. The conditions consist of varying ratios of front-to-back energy and varying levels of cross-correlated reverberant energy. Head movements are monitored in terms of angular rotation using a head tracker while listeners are prompted to assign subjective ratings of LEV and ASW. The tests are repeated while listeners are asked to keep their heads fixed. Head movements are analysed and results of the tests are compared.
