Abstract [en]

Whether to improve existing soundscapes or to design future soundscapes it is central to have a prediction model that can guide our actions in order to achieve desired outcomes. In order to create such a predication model it is necessary to understand the psychological processes that underlie soundscape perception. In the present paper I outline a theoretic framework for such psychological processes. I propose that Information Load is the most fundamental dimensions underlying soundscape perception and the cause of emotional responses to soundscapes. In this context information load is an interaction between soundscape complexity and our ability to comprehend or to process information. The framework predicts that low degree of information load (a monotonous soundscape) is boring, a moderate degree of information load (a quiet natural soundscape) is pleasant, above moderate degree of information load (an eventful soundscape) is exciting, and a very high degree of information load (a chaotic soundscape) is unpleasant. In addition, I propose promising indicators of information load, like 1/f-like noise, which may be used to test the proposed framework.
