This study treats both landscape design and soundscape design as similar processes of reproduction and practice. In the process of designing landscape, designers create simple ambiguous shapes not found in previous landscape in both landscape and soundscape design. Landscape designers make stylised shapes to avoid more natural shapes that they dislike. Soundscape designers do the same thing,but they also want to make original objects that appeal to them and have never existed before. The totality of landscape can be felt as a reflection of the designer’s subjectivity rather than an integral object. Simple geometric shapes are considered to reflect the feelings experienced by the designer, and these ambiguous shapes can be contrasted with actual objects in experiencing landscape.
