Abstract

Previous studies of soundscape have tried to understand the relationship between sound objects and soundscape rating, resulting in the categorisation of general sound objects according to positive or negative perceptions. This study tries to determine the relationship and interaction between specific sound objects in a soundscape and the soundscape dimensions.

This study is divided into four steps: testing the validity of soundscape study in the laboratory, the application of soundscape recording, the development of a soundscape environment simulator, and the determination of the relationship between specific sound objects and soundscape dimensions according to expectations and preferences regarding sound objects.

The first step confirms three reliable soundscape dimensions from in situ and laboratory experiments (measured using the same semantic scales for both): Relaxation, Dynamics and Communication. It also confirms the validity of laboratory experiments compared with in situ ones. Furthermore, the effect of sound level adjustment on soundscape reproduction in the laboratory is investigated. The second step, using soundscape recording, confirms that the common method of analysing the relationship between sound objects and soundscape rating (in situ experiment and soundscape reproduction) is not adequate due to limitations in the selection of sound objects and control over their parameters. A different method is proposed to deal with these limitations: using a soundscape environment simulator.

A soundscape environment simulator is therefore developed to understand the relationship and interaction between sound objects in a soundscape and the perception of the soundscape. The soundscape environment simulator can be used to compose complex soundscapes. Furthermore, semantic differential analysis confirms that soundscape composition can represent an actual soundscape.

Finally, two experiments are conducted using the soundscape environment simulator to study expectations and preferences of sound objects in a soundscape. The study succeeds in explaining the relationship and interaction between specific sound objects and the rating of soundscape. Furthermore, a perception model regarding the preference of sound objects used in the soundscape environment simulator and the soundscape dimensions is developed and implemented in the soundscape environment simulator. This implementation allows the simulator to predict perceptions of the soundscapes composed by the simulator.
