Abstract
In virtual acoustics or artificial reverberation, impulse responses can be
split so that direct and reflected components of the sound field are
reproduced via separate loudspeakers. The authors had investigated the
perceptual effect of angular separation of those components in commonly
used 5.0 and 7.0 multichannel systems, with one and three sound sources
respectively (Kleczkowski et al., 2015, J. Audio Eng. Soc. 63, 428-443).
In that work, each of the front channels of the 7.0 system was fed with
only one sound source. In this work a similar experiment is reported, but
with phantom sound sources between the front loud- speakers. The
perceptual advantage of separation was found to be more consistent than in
the condition of discrete sound sources. The results were analysed both
for pooled listeners and in three groups, according to experience. The
advantage of separation was the highest in the group of experienced
listeners.
