Abstract
Previous studies have looked at how different concert halls with
different lateral reflections affect apparent source width. Yet, the
perceptual effects of different source distributions with different
recording techniques on apparent source width are not well understood.
This study explores how listeners perceive the width
of an orchestra by using four stereo and one binaural recording
techniques and three wave field synthesis ensemble settings. Subjective
experiments were conducted using stereo loudspeakers and
headphone to play back the recording clips asking the listeners to
rate the perceived wideness of the sound source. Results show that
recording techniques greatly influence how wide an orchestra is
perceived. The primary mechanism used to judge auditory spatial
impression differs between stereo loudspeaker and headphone
listening. When western classical symphony is recorded and reproduced
by two-channel stereophony, the changes in instrument
positions in terms of increasing or reducing the physical source
width do not lead to an obvious increase or reduction on the spatial
impression of the performing entity.
