ABSTRACT
This chapter focuses on GIS-based approaches to mapping sound varies, from displaying large areas like cities or agglomerations to the description of single streets or public green spaces. The study of environmental music the use of nature sounds to enrich musical pieces or compose entirely new ones involves an understanding of the importance of sound for all people who are capable of hearing. The use of only "real" environmental sounds suggests that acoustic ecology's soundscape composers could express the natural soundscape in their artistic collages. Most diverse approaches lead to numerous results that vary from technological accuracy to individual originality. Acoustic ecology's individual approaches to sound recording from the 1970s have mostly been replaced by more quantitative techniques and modern GIS models. The Austin study aims to at finding a way to describe the soundscape of a specific area, district, or quarter of a city.
