    Sammanfattning : Phonocardiographic signals contain bioacoustic information reflecting the operation of the heart. Normally there are two heart sounds, and additional sounds indicate disease. If a third heart sound is present it could be a sign of heart failure whereas a murmur indicates defective valves or an orifice in the septal wall. LÄS MER

    Sammanfattning : Listen. If I ask you to listen, what is it that I ask of you—that you will understand, or perhaps obey? Or is it some sort of readiness that is requested? What occurs with a body in the act of listening? How do sound and voice structure audio-visual-spatial relations in concrete situations?This doctoral thesis in fine arts consists of six artworks and an essay that documents the research process, or rather, acts as a travelogue as it stages and narrates a series of journeys into a predominantly sonic ecology.
