How can we model a quality event? Some considerations on describing quality judgment and prediction processes
Sebastian Möller · The Journal of the Acoustical Society of America · 2008
Jens Blauert has introduced a systemic view on a listener in an auditory experiment. This view helps to separate sound events from auditory events and from their descriptions, and to identify and describe the processes involved in such experiments. The notion has later been extended to listeners in a quality judgment situation by Jekosch and Raake, leading to the notion of a "quality event". On the one hand, knowledge of the involved processes is necessary to design appropriate measurement processes for, e.g., sound quality, transmission quality, auditory-scene quality, or product-sound quality. On the other hand, such knowledge enables us to define algorithms which estimate quality - or sub-aspects of it - in the system design process. The talk will mainly follow the second line and will identify components which are necessary for an algorithmic description of the processes involved in the formation of a quality event. Taking the example of telecommunication services, it will be shown which components of quality prediction models are already available, and which others are still out-of-reach and require further study.
