The soundscape is the component of the acoustic environment that can be perceived by humans. There is a varied history of the use of soundscape depending on discipline - ranging from urban design to wildlife ecology. An important distinction is to separate soundscape from the broader term acoustic environment. The acoustic environment is the combination of all the acoustic resources within a given area - natural sounds and human-caused sounds – as modified by the environment. The International Organization for Standardization (ISO) standardized these definitions in 2014.([https://www.iso.org/obp/ui/#iso:std:iso:12913:-1:ed-1:v1:en ISO 12913-1:2014])
