Abstract
Sound quality is an important aspect in many sound reproduction applications. In recent years sensory evaluation techniques have been gaining popularity for the detailed perceptual assessment of device sound characteristics. From the literature, hundreds of descriptors can be found to describe the nature of sound quality and this often becomes the focus of debate among researchers, rather than the product development itself. In an effort to shift the focus back to the areas of importance, i.e., the product, this study seeks to define a common terminology, a lexicon, for the characterization of sound quality in loudspeakers, headphones, or other sound reproduction systems. The study summarized the gathering of descriptors for sound character from the literature and then experimental leading to a structure protocol of perceptual sound quality attributes for this domain of application. A structured sound wheel is presented comprising of different layers of attributes. For each attribute, definitions have been developed with associated sound samples for training. The paper presents the on-going development process, including validation of attributes and their definitions.
