Investigating Perceptual Effects Associated with Vertically Extended Sound Fields Using Virtual Ceiling Speaker

Document Thumbnail

Virtual Ceiling Speaker (VCS) is a signal processing method that creates an elevated auditory image using an optimized cross-talk compensation for a 5-channel reproduction system. In order to understand latent perceptual effects caused by virtually elevated sound imageries, we experimentally compared physically and virtually elevated sound sources and elicited four salient attributes: ASW, LEV, Powerfulness, and Clarity. The subsequent listening experiment revealed that listeners perceived higher LEV or Clarity when physically or virtually elevated early reflections were added, compared to conventional 5-channel content. The observed perceptual characters were partly associated with two physical parameters: loudness difference and correlation between the Center signal and virtual speaker signal.
