Man experiences his environment through his senses. When we walk into a room, our first impression is a visual one. But information is also being taken in through our hearing. We register the sound of the floor as we walk across it, the echo of our voices, and whether the room is quiet or loud. In this article I would like to explore acoustic perception, the phenomenon of acoustics and ways of designing for it. Ingrid Bobran-Wittfoht, Dirk Schlauch
