With her PhD on meaningful associations of products’ sounds, Özcan’s recent research focuses on the perceptual and cognitive processes underlying meaning attribution to product experiences. She has published in several peer-reviewed international journals and has recently been a guest editor for the Journal of Sonic Studies’ special issue on Sound Design (2014). Elif Özcan is an Assistant Professor at the Faculty of Industrial Design Engineering of Delft University of Technology. International Journal of Design, 8(3), 97-111.ĭr. Product sounds: Basic concepts and categories. This study provides insights into the perceptual attributes of product sounds and their cognitive relevance from the users’ perspective and discusses the findings in relation to overall product experience and product (sound) design.Ĭitation: Özcan, E., van Egmond, R., & Jacobs, J. Relevance to Design Practice – Product sound design (PSD) is an emerging topic within the field of product development. Keywords – Product Sounds, Sound Categories, Multi-sensory Design, Sound Design, Categorization. In addition, this paper presents two methods for the perceptual evaluation of product sounds. We conclude that sound is an intrinsic property of a product and, with the knowledge gathered in this study, designers will be able to relate the auditory property of a product to the overall product experience. The results indicate that these categories are not only a direct consequence of perceptual similarities in the spectral temporal structure but also result from similarities based on cognitive, emotional, and contextual evaluations of the sound. Employing two different experimental paradigms (free categorization and pairwise comparison), we determined six perceptually relevant product sound categories (air, alarm, cyclic, impact, liquid, mechanical) and nine basic concepts that mentally represent these categories (sound source, action, location, sound type, onomatopoeias, psychoacoustics, temporal descriptions, emotions, abstract meaning). We explored the perceptual domain of product sounds in order to be able to derive perceptually similar categories and determine how users are able to describe these categories by merely listening to them. In this paper we investigated which categories of product sounds listeners can distinguish.
