In our modern society sound is almost constantly present. In pre-historic times, there were more of silence. Our listening habits depend on the sound in our environment, but the meaning attached to sound also determine how and what we listen to. Certain sounds are considered more important to listen to, other less. Can we even understand how people listened in pre-historic times and what did the world sound like? And what do we know about the soundscapes that they produced with voice and instruments?  These are some of the interesting questions music archaeologist Cajsa S. Lund will try to answer in her talk. She will also bring a large number of ancient sound devices that she will demonstrate and talk about.
