Abstract

An experiment to determine the perceptual attributes of the experience of listening to a target audio program in the presence of an audio interferer was performed. The first stage was a free elicitation task in which a total of 572 phrases were produced. In the second stage, a consensus vocabulary procedure was used to reduce these phrases into a comprehensive set of attributes. Groups of experienced and inexperienced listeners determined nine and eight attributes, respectively. These attribute sets were combined by the listeners to produce a final set of 12 attributes: masking, calming, distraction, separation, confusion, annoyance, environment, chaotic, balance and blend, imagery, response to stimuli over time, and short-term response to stimuli. In the third stage, a simplified ranking procedure was used to select only the most useful and relevant attributes. Four attributes were selected: distraction, annoyance, balance and blend, and confusion. Ratings using these attributes were collected in the fourth stage, and a principal component analysis performed. This suggested two dimensions underlying the perception of an audio-on-audio interference situation: The first dimension was labeled "distraction" and accounted for 89% of the variance; the second dimension, accounting for 10% of the variance, was labeled "balance and blend."
