What does a world without people sound like? Is it even possible to imagine this paradox? Because if there are no more people, there are no more human ears that could hear this world. What is hard to imagine can nevertheless be felt, one can try to present an invented idea of a sound world without man-made sounds. The danger of such an invented idea lies in the strong, all-too-human subjectivity of this process. I have tried to avoid this danger by making it clear that man-made structures will have their consequences for the new world long after man has gone. What do these echoes of human civilisation sound like? What do slowly decaying cities sound like? Another way out of subjectivity was to listen to already existing worlds "after man", this on the basis of sound recordings of bats from Tchernobyl, which fortunately Professor Timothy Mousseau sent me in the process. Professor Mousseau is a specialist in the field of adaptive evolution - he studies the animals and plants of contaminated sites and how they have adapted to radiation over the years. The echoes of sound-polluted civilisation as well as the echoes of irradiated bats have blended into a soundscape that for me comes close to the paradox of "What does a world without humans sound like?" but also to the future vision of a world of flat ontology.
