Sound and soundscape classification: establishing key auditory dimensions and their relative importance
MetadataShow full item record
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.
