Soundscape simulator as a tool to predict the perception of acoustic environment

Sudarsono, AS; Lam, YW; Davies, WJ

Abstract

Previous studies have shown relationships between sound objects by grouping general sound objects
according to how people perceive them (i.e. positively or negatively), but not according to how specific
sound objects and their interaction affect soundscape perception. Soundscape composition using an acoustic
environment simulator is introduced to address this problem. By using soundscape composition, experiments
can be conducted in which sound objects and their parameters are selected and controlled in a soundscape.
An acoustic environment simulator is a system which allows soundscape composition by controlling the
parameters of sound objects, enabling participants to compose a soundscape against their expectations. In this
study, the acoustic environment simulator is applied to understand the relationship between the sound objects
and the perceptual dimensions of the soundscape (Relaxation, Dynamic, and Communication). Furthermore,
the mathematical model of the relationship has been successfully implemented in the simulator. The
implementation allows the acoustic environment simulator to predict the perception of the acoustic
environment composed using the simulator. This system will significantly help soundscape designers and
urban planners to test soundscape design or ameliorate negative soundscapes.
