Spatial Sound With Loudspeakers and Its Perception: A Review of the Current State

Abstract: This paper reviews the current state of loudspeaker-based spatial sound reproduction methods from technical perspective as well as perceptual perspective. A nomenclature is developed that allows for a strict separation between these two perspectives. The physical fundamentals, practical realization, and results from perceptual studies are discussed for a number of well-established and emerging reproduction techniques. Further, the paper outlines novel approaches to spatial sound evaluation in terms of perceived quality and provides a comparison of current approaches.

PhysioSonic - evaluated movement sonification as auditory feedback in physiotherapy

Abstract: We detect human body movement interactively via a tracking system. This data is used to synthesize sound and transform sound files (music or text). A subject triggers and controls sound parameters with his or her movement within a pre-set range of motion. The resulting acoustic feedback enhances new modalities of perception and the awareness of the body movements. It is ideal for application in physiotherapy and other training contexts. The sounds we use depend on the context and aesthetic preferences of the subject. On the one hand, metaphorical sounds are used to indicate the leaving of the range of motion or to make unintended movements aware. On the other hand, sound material like music or speech is played as intuitive means and motivating feedback to address humans. The sound material is transformed in order to indicate deviations from the target movement. PhysioSonic has been evaluated with a small study on 12 patients with limited shoulder mobility. The results show a clear benefit for most patients, who also report on PhysioSonic being an enrichment of their therapeutic offer.
