Infrasound is characterized by an ability to get around obstacles with little dissipation. In music, acoustic waveguide methods, such as a large pipe organ or, for reproduction, exotic loudspeaker designs such as transmission line, rotary woofer, or traditional subwoofer designs can produce low-frequency sounds, including near-infrasound.
Prehistoric music. Prehistoric music (previously called primitive music) is a term in the history of music for all music produced in preliterate cultures ( prehistory ), beginning somewhere in very late geological history. Prehistoric music is followed by ancient music in different parts of the world, but still exists in isolated areas.
Natural sounds. Natural sounds are any sounds produced by non-human organisms as well as those generated by natural, non-biological sources within their normal soundscapes. It is a category whose definition is open for discussion. Natural sounds create an acoustic space . The definition of the soundscape can be broken down into three components ...
Evolutionary musicology. Evolutionary musicology is a subfield of biomusicology that grounds the cognitive mechanisms of music appreciation and music creation in evolutionary theory. It covers vocal communication in other animals, theories of the evolution of human music, and holocultural universals in musical ability and processing.
The adoption of sound-on-film also helped movie-industry audio engineers to make rapid advances in the process we now know as multi-tracking, by which multiple separately-recorded audio sources (such as voices, sound effects and background music) can be replayed simultaneously, mixed together, and synchronized with the action on film to create ...
Biomusic is a form of experimental music which deals with sounds created or performed by non-humans. The definition is also sometimes extended to include sounds made by humans in a directly biological way. For instance, music that is created by the brain waves of the composer can also be called biomusic as can music created by the human body ...
Perception of infrasound. Infrasound is sound at frequencies lower than the low frequency end of human hearing threshold at 20 Hz. It is known, however, that humans can perceive sounds below this frequency at very high pressure levels. [ 1] Infrasound can come from many natural as well as man-made sources, including weather patterns ...
Psychoacoustics is the branch of psychophysics involving the scientific study of the perception of sound by the human auditory system. It is the branch of science studying the psychological responses associated with sound including noise, speech, and music. Psychoacoustics is an interdisciplinary field including psychology, acoustics ...
