Sound and soundscape classification: establishing key auditory dimensions and their relative importance

Abstract

This paper investigates soundscape classification by using two different forms of data gathering and two different populations. The first method involves a questionnaire completed by 75 audio professionals. The second uses a speak-aloud experiment, during which 40 end users were asked to describe their audio environment. While both approaches are different and target a different audience, they provide an indication of key dimensions for the perception of soundscapes and their relative importance. Contrasts and similarities between the results of the questionnaire and speak-alouds are highlighted. Their implications with regards to the establishment of a set of common terms in order to aid future auditory designs are also discussed.
