Acoustic ecology, sometimes called ecoacoustics or "soundscape studies, is a discipline studying the relationship, mediated through sound, between human beings and their "environment. Acoustic ecology studies started in the late 1960s with "R. Murray Schafer and his team at "Simon Fraser University ("Vancouver, British Columbia, "Canada) as part of the "World Soundscape Project. The original WSP team included "Barry Truax and "Hildegard Westerkamp, Bruce Davies and Peter Huse, among others. The first study produced by the WSP was titled The Vancouver Soundscape. The interest in this area grew enormously after this pioneer and innovative study and the area of acoustic ecology raised the interest of researchers and artists all over the world. In 1993, the members of the by now large and active international acoustic ecology community formed the World Forum of Acoustic Ecology.
Every three years since the WFAE's founding at "Banff, "Canada in 1993, an international symposium has taken place. "Stockholm, "Amsterdam, "Devon, "Peterborough, and "Melbourne followed. In November 2006, the WFAE meeting took place in "Hirosaki, Japan. "Koli, "Finland, was the meeting place of the latest WFAE world conference["dead link].
From its roots in the sonic sociology and radio art of Schafer and his colleagues, acoustic ecology has found expression in many different fields. While most have taken some inspiration from Schafer's writings, in recent years there have also been healthy divergences from the initial ideas. Among the expanded expressions of acoustic ecology are increasing attention to the sonic impacts of "road and airport construction, widespread networks of "phonographers" exploring the world through sound, the broadening of "bioacoustics (the use of sound by animals) to consider the subjective and objective responses of animals to human noise, including increasing use of the idea of "acoustic ecology" in the literature, and a popular in the effects of human noise on animals, with ocean noise capturing the most attention. Acoustic ecology finds expression in many different fields, including niches as unique as historical soundscapes and psychosonography.
Noise is generally a by-product of increased urbanization and development. Noise can alter the acoustic environment of aquatic and terrestrial habitats. Bird diversity has shown to decline because of chronic noise levels in cities and along roadways. Some species such as the urban great tits have changed the frequency of there calls to adapt. In terms of evolution, man-made noise is a much more recent phenomenon. Scientific research has shown that it has potential to change behavior, alter physiology and even restructure animal communities. 
"Dominion" takes listeners on an "acoustic journey across "Canada. The work begins with the firing of the "Noon Gun in "St. John's harbour in "Newfoundland and continues westward, recording sounds such as the Peace Tower bell in "Ottawa and the O Canada Horn in "Vancouver, along the way. A 12-piece "orchestra, representing the 10 "provinces and then two "territories, carries listeners through the work, along with the whistle of a "Canadian Pacific Railway train, representing the railroad that first connected Canada over a century ago.
Marc E. Moglen (2007) recreated pre-historical "Soundscapes (Acoustic Ecology) at "University of California, Berkeley's Department of Anthropology, combining compositional techniques with site recordings for a non-diegetic piece in the virtual world of Second Life, on "Okapi Island". At the Center for New Media the acoustic ecological setting of the former jazz scene in Oakland, CA was developed for a virtual world setting.
