Soundscapes Lecture
Perception, Soundscapes and Science
Sound can be studied from various perspectives. This contribution
will give
an overview over some different approaches. The first is the physical
approach, in which sound production is modeled on the basis of
mathematical
equations or of computer models of the sound-generating event. The
second
approach, referred to as auditory scene analysis, studies the
perceptual
process in which some sound components are attributed to the same
sound-generating event, while some others are perceptually attributed
to
different events. In this way, the listeners constructs an auditory
scene,
an image of the sound-generating events occurring in his or her
surroundings. The last approach we will deal with is called the
ecological
approach. According to this approach, the listener does not so much
listen
to the pitch, the timbre or the rhythm of the sound but, on the basis
of the
physical cues in the sound, mentally reconstructs an image of the
environment and of what happens in that environment. The implications
of
this for the design of soundscapes, and of user-interface sounds in
particular, will be discussed.
