For the sound installation, the unconscious sounds that the author's body makes during daily life activities were recorded, such as the sound of breathing, heartbeat and chewing in the stomach. These sounds were transmitted through speakers located outside the exhibition space. Inside the exhibition space, a video documentary was shown in which a cardiologist examined the author's heartbeat using non-invasive techniques. This work addresses the issue of our perception of the creation of human feelings, exploring how intimate, internal sounds of the body are translated by medical devices into visual and verbal images. The author explores the different roles that imagination, experience and technology play in our understanding and interaction with the world around us.
