Sound installation (related to sound art and sound sculpture) is an intermedia and time based art form. It is an expansion of an art installation in the sense that it includes the sound element and therefore the time element. The main difference with a sound sculpture is that a sound installation has a three-dimensional space and the axes with which the different sound objects are being organized are not exclusively internal to the work, but also external. A work of art is an installation only if it makes a dialog with the surrounding space. A sound installation is usually a site-specific but sometimes it can be readapted to other spaces. It can be made either in close or open spaces, and context is fundamental to determine how a sound installation will be aesthetically perceived.The diffe
