Abstract

This paper is twofold: 1) it describes a comparative study between two listening tests methodologies and 2) presents a new soundscape assessment tool based on a multichannel loudspeaker setup and sonic interaction. The goal of this research is to enhance soundscape assessment methodologies by improving the quality and validity of laboratorial testing. Our proposal builds upon the concepts of “ecological validity” of auditory stimuli and “representative design” of the listening experience, both introduced by [1] in the context of psychological experiments on perception. Results suggest that representative design (mimicking real-world settings in laboratory) in soundscapes listening tests is better achieved through surround systems than binaural systems (using headphones). Moreover, users agree that the interactive system for real- time soundscape design helps raising awareness for the soundscape and auditory phenomena.
