Abstract:
Some
results from perceptual experiments on high-resolution audio show that sounds
with only frequency components over 20kHz cannot be perceived, while these
components become perceptually effective when they are delivered with the frequency components of the audible
frequencies. The first factor to be considered will be non-linearity in each
stage from recording to perception: pick-up systems, experimental setup
including filters and loudspeakers, air propagation and the auditory system. We
would like to discuss the items focusing on perceptual inter-modulation effects
caused by non-linearity in loudspeakers, filters, air-propagation and auditory
system in this workshop.
