Soundscape studies have a rich tradition[1],[2],[3],[4],[5]. Because the field has evolved differently around the world, as well as across disciplines, there is a diversity of opinions about its definition and aims. Consequently, the use of the term ‘soundscape’ has become idiosyncratic and ambiguous[6].

This International Standard aims to enable a broad international consensus on the definition of ‘soundscape’, to provide a foundation for communication across disciplines and professions with an interest in soundscape.

There are similarities between the concepts of 'landscape'[7] and 'soundscape'; both are based on perception by people. For the purpose of this International Standard, soundscape will be understood as a perceptual construct, related to a physical phenomenon. The standard distinguishes the perceptual construct (soundscape) from the physical phenomenon (acoustic environment), and clarifies that soundscape exists through human perception of the acoustic environment.
