Soundscape

From Wikipedia, the free encyclopedia

Jump to: navigation, search

A soundscape is a sound or combination of sounds that forms or arises from an immersive environment. The study of soundscape is the subject of acoustic ecology. The idea of soundscape refers to both the natural acoustic environment, consisting of natural sounds, including animal vocalizations and, for instance, the sounds of weather and other natural elements; and environmental sounds created by humans, through musical composition, sound design, and other ordinary human activities including conversation, work, and sounds of mechanical origin resulting from use of industrial technology. The disruption of these acoustic environments results in noise pollution.

The term "soundscape" can also refer to an audio recording or performance of sounds that create the sensation of experiencing a particular acoustic environment, or compositions created using the "found sounds" of an acoustic environment, either exclusively or in conjunction with musical performances.[1][2]

[edit] Elements

Pauline Oliveros, composer of post-World War II electronic art music, defined the term "soundscape" as "All of the waveforms faithfully transmitted to our audio cortex by the ear and its mechanisms".[3]

According to author, composer and environmentalist, R. Murray Schafer, there are three main elements of the soundscape:

  • Keynote sounds
This is a musical term that identifies the key of a piece, not always audible… the key might stray from the original, but it will return. The keynote sounds may not always be heard consciously, but they “outline the character of the people living there” (Schafer). They are created by nature (geography and climate): wind, water, forests, plains, birds, insects, animals. In many urban areas, traffic has become the keynote sound.
  • Sound signals
These are foreground sounds, which are listened to consciously; examples would be warning devices, bells, whistles, horns, sirens, etc.
  • Soundmark
This is derived from the term landmark. A soundmark is a sound which is unique to an area.

In his 1977 book, The Tuning of the World, Schafer wrote, “Once a Soundmark has been identified, it deserves to be protected, for soundmarks make the acoustic life of a community unique”.

[edit] Soundscapes in music

In music, soundscape compositions are often a form of electronic music, or electroacoustic music. Composers who use soundscapes include real-time granular synthesis pioneer Barry Truax and Luc Ferrari, whose Presque rien, numéro 1 (1970) is an early soundscape composition. [4][2]

Music soundscapes can also be generated by automated software methods, such as the experimental TAPESTREA application, a framework for sound design and soundscape composition, and others. [5][6]

The soundscape is often the subject of mimicry in Timbre-centered music such as Tuvan throat singing. The process of Timbral Listening is used to interpret the timbre of the soundscape. This timbre is mimicked and reproduced using the voice or rich harmonic producing instruments.[7]

[edit] Soundscapes in health care

Soundscapes from a computerized acoustic device with a camera may also offer synthetic vision to the blind, utilizing human echolocation, as is the goal of the seeingwithsound project.[8]

[edit] Soundscapes and noise pollution

Papers on noise pollution are increasingly taking a holistic, soundscape approach to noise control. Whereas acoustics tends to rely on lab measurements and individual acoustic characteristics of cars and so on, soundscape takes a top-down approach. Drawing on John Cage's ideas of the whole world as composition, soundscape researchers investigate people's attitudes to soundscapes as a whole rather than individual aspects - and look at how the entire environment can be changed to be more pleasing to the ear.
