Natural Sounds And Night Skies Division
A soundscape is the acoustic environment as perceived by humans, in context. The term was originally coined by Michael Southworth, and popularised by R. Murray Schafer. There is a varied history of the use of soundscape depending on discipline, ranging from urban design to wildlife ecology to computer science. An important distinction is to separate soundscape from the broader acoustic environment. The acoustic environment is the combination of all the acoustic resources, natural and artificial, within a given area as modified by the environment. The International Organization for Standardization (ISO) standardized these definitions in 2014.ISO 12913-1:2014 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 or soundscape ecology. The idea of soundscape refers to both the natural acoustic environment, consisting of natural sounds, including animal vocalizations, the ...

Biophysical Environment
A biophysical environment is a biotic and abiotic surrounding of an organism or population, and consequently includes the factors that have an influence in their survival, development, and evolution. A biophysical environment can vary in scale from microscopic to global in extent. It can also be subdivided according to its attributes. Examples include the marine environment, the atmospheric environment and the terrestrial environment. The number of biophysical environments is countless, given that each living organism has its own environment. The term ''environment'' can refer to a singular global environment in relation to humanity, or a local biophysical environment, e.g. the UK's Environment Agency. Life-environment interaction All life that has survived must have adapted to the conditions of its environment. Temperature, light, humidity, soil nutrients, etc., all influence the species within an environment. However, life in turn modifies, in various forms, its conditions ...

Anthropophony
Soundscape ecology is the study of the acoustic relationships between living organisms, human and other, and their environment, whether the organisms are marine or terrestrial. First appearing in the ''Handbook for Acoustic Ecology'' edited by Barry Truax, in 1978, the term has occasionally been used, sometimes interchangeably, with the term acoustic ecology. Soundscape ecologists also study the relationships between the three basic sources of sound that comprise the soundscape: those generated by organisms are referred to as the biophony; those from non-biological natural categories are classified as the geophony, and those produced by humans, the anthropophony. Increasingly, soundscapes are dominated by a sub-set of anthropophony (sometimes referred to in older, more archaic terminology as "anthropogenic noise"), or technophony, the overwhelming presence of electro-mechanical noise. This sub-class of noise pollution or disturbance may produce a negative effect on a wide range of ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Granular Synthesis
Granular synthesis is a sound synthesis method that operates on the microsound time scale. It is based on the same principle as sampling. However, the samples are split into small pieces of around 1 to 100 ms in duration. These small pieces are called grains. Multiple grains may be layered on top of each other, and may play at different speeds, phases, volume, and frequency, among other parameters. At low speeds of playback, the result is a kind of soundscape, often described as a cloud, that is manipulatable in a manner unlike that for natural sound sampling or other synthesis techniques. At high speeds, the result is heard as a note or notes of a novel timbre. By varying the waveform, envelope, duration, spatial position, and density of the grains, many different sounds can be produced. Both have been used for musical purposes: as sound effects, raw material for further processing by other synthesis or digital signal processing effects, or as complete musical works in the ...

Electroacoustic Music
Electroacoustic music is a genre of popular and Western art music in which composers use technology to manipulate the timbres of acoustic sounds, sometimes by using audio signal processing, such as reverb or harmonizing, on acoustical instruments. It originated around the middle of the 20th century, following the incorporation of electric sound production into compositional practice. The initial developments in electroacoustic music composition to fixed media during the 20th century are associated with the activities of the at the ORTF in Paris, the home of musique concrète, the Studio for Electronic Music in Cologne, where the focus was on the composition of ''elektronische Musik,'' and the Columbia-Princeton Electronic Music Center in New York City, where tape music, electronic music, and computer music were all explored. Practical electronic music instruments began to appear in the early 20th century. Tape music Tape music is an integral part of ''musique concrète' ...

Electronic Music
Electronic music is a genre of music that employs electronic musical instruments, digital instruments, or circuitry-based music technology in its creation. It includes both music made using electronic and electromechanical means ( electroacoustic music). Pure electronic instruments depended entirely on circuitry-based sound generation, for instance using devices such as an electronic oscillator, theremin, or synthesizer. Electromechanical instruments can have mechanical parts such as strings, hammers, and electric elements including magnetic pickups, power amplifiers and loudspeakers. Such electromechanical devices include the telharmonium, Hammond organ, electric piano and the electric guitar."The stuff of electronic music is electrically produced or modified sounds. ... two basic definitions will help put some of the historical discussion in its place: purely electronic music versus electroacoustic music" ()Electroacoustic music may also use electronic effect uni ...

World Soundscape Project
The World Soundscape Project (WSP) was an international research project founded by Canadian composer R. Murray Schafer in the late 1960s at Simon Fraser University. The project initiated the modern study of acoustic ecology. Its ultimate goal is "to find solutions for an ecologically balanced soundscape where the relationship between the human community and its sonic environment is in harmony." The practical manifestations of this goal include education about the soundscape and noise pollution, in addition to the recording and cataloguing of international soundscapes with a focus on preservation of soundmarks and dying sounds and sound environments. Publications which emerged from the project include ''The Book of Noise'' (1968) and ''The Tuning of the World'' (1977), both by Schafer, as well as the ''Handbook for Acoustic Ecology'' (1978) by Barry Truax. The project has thus far resulted in two major tours, in Canada and Europe, the results of which comprise the World Soundscape ...

World War II
World War II or the Second World War, often abbreviated as WWII or WW2, was a world war that lasted from 1939 to 1945. It involved the vast majority of the world's countries—including all of the great powers—forming two opposing military alliances: the Allies and the Axis powers. World War II was a total war that directly involved more than 100 million personnel from more than 30 countries. The major participants in the war threw their entire economic, industrial, and scientific capabilities behind the war effort, blurring the distinction between civilian and military resources. Aircraft played a major role in the conflict, enabling the strategic bombing of population centres and deploying the only two nuclear weapons ever used in war. World War II was by far the deadliest conflict in human history; it resulted in 70 to 85 million fatalities, mostly among civilians. Tens of millions died due to genocides (including the Holocaust), starvation, massa ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Pauline Oliveros
Pauline Oliveros (May 30, 1932 – November 24, 2016) was an American composer, accordionist and a central figure in the development of post-war experimental and electronic music. She was a founding member of the San Francisco Tape Music Center in the 1960s, and served as its director. She taught music at Mills College, the University of California, San Diego (UCSD), Oberlin Conservatory of Music, and Rensselaer Polytechnic Institute. Oliveros authored books, formulated new music theories, and investigated new ways to focus attention on music including her concepts of "deep listening" and "sonic awareness", drawing on metaphors from cybernetics. She was an Eyebeam resident. Early life and career Oliveros was born in Houston, Texas. She started to play music as early as kindergarten, and at nine years of age she began to play the accordion, received from her mother, a pianist, because of its popularity in the 1940s.Baker, Alan"An interview with Pauline Oliveros" January 2003.

Found Object (music)
Found objects are sometimes used in music, often to add unusual percussive elements to a work. Their use in such contexts is as old as music itself, as the original invention of musical instruments almost certainly developed from the sounds of natural objects rather than from any specifically designed instruments. Use in classical and experimental music The use of found objects in modern classical music is often connected to experiments in indeterminacy and aleatoric music by such composers as John Cage and Karlheinz Stockhausen, although it has reached its ascendancy in those areas of popular music as well, such as the ambient works of Brian Eno. In Eno's influential work, found objects are credited on many tracks. The ambient music movement which followed Eno's lead has also made use of such sounds, with notable exponents being performers such as Future Sound of London and Autechre, and natural sounds have also been incorporated into many pieces of new-age music.

Performance
A performance is an act of staging or presenting a play, concert, or other form of entertainment. It is also defined as the action or process of carrying out or accomplishing an action, task, or function. Management science In the work place, job performance is the hypothesized conception or requirements of a role. There are two types of job performances: contextual and task. Task performance is dependent on cognitive ability, while contextual performance is dependent on personality. Task performance relates to behavioral roles that are recognized in job descriptions and remuneration systems. They are directly related to organizational performance, whereas contextual performances are value-based and add additional behavioral roles that are not recognized in job descriptions and covered by compensation; these are extra roles that are indirectly related to organizational performance. Citizenship performance, like contextual performance, relates to a set of individual activity/co ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Audio Recording
Sound recording and reproduction is the electrical, mechanical, electronic, or digital inscription and re-creation of sound waves, such as spoken voice, singing, instrumental music, or sound effects. The two main classes of sound recording technology are analog recording and digital recording. Sound recording is the transcription of invisible vibrations in air onto a storage medium such as a phonograph disc. The process is reversed in sound reproduction, and the variations stored on the medium are transformed back into sound waves. Acoustic analog recording is achieved by a microphone diaphragm that senses changes in atmospheric pressure caused by acoustic sound waves and records them as a mechanical representation of the sound waves on a medium such as a phonograph record (in which a stylus cuts grooves on a record). In magnetic tape recording, the sound waves vibrate the microphone diaphragm and are converted into a varying electric current, which is then converted t ...
