Training of Listeners for Evaluation of Spatial Attributes of Sound
AES Convention 117 · Paper 6237 · October 2004
Abstract
A group of listeners were engaged in training to learn to evaluate auditory source width (ASW) and listener envelopment (LEV). The training consisted of discussions on perception of spatial sound and visualization of both attributes with drawings. After each session the subjects evaluated the ASW and LEV of a set of stimuli consisting of different source signals simulated in a few chosen acoustical environments. Most subjects developed consistent criteria for their judgements and maintained them throughout the training and a subsequent control two months later. However, considerable individual differences were found. Analysis of the data revealed that large part of the differences was due to different judgements between the chosen source signals. The training also suggested that some differences could have been caused by the translation from multi-dimensional perception to the unidimensional judgements. A further graphical evaluation of the stimuli showed that this was not the case.
