Acoustics is a branch of physics that deals with the study of mechanical waves in gases, liquids, and solids including topics such as vibration, sound, ultrasound and infrasound. A scientist who works in the field of acoustics is an acoustician while someone working in the field of acoustics technology may be called an acoustical engineer. The application of acoustics is present in almost all aspects of modern society with the most obvious being the audio and noise control industries.
Perception is the organization, identification, and interpretation of sensory information in order to represent and understand the presented information or environment. All perception involves signals that go through the nervous system, which in turn result from physical or chemical stimulation of the sensory system. Vision involves light striking the retina of the eye; smell is mediated by odor molecules; and hearing involves pressure waves.
Ambient music is a genre of music that emphasizes tone and atmosphere over traditional musical structure or rhythm. It may lack net composition, beat, or structured melody. It uses textural layers of sound that can reward both passive and active listening and encourage a sense of calm or contemplation. The genre is said to evoke an "atmospheric", "visual", or "unobtrusive" quality. Nature soundscapes may be included, and the sounds of acoustic instruments such as the piano, strings and flute may be emulated through a synthesizer.
Auditory illusions are false perceptions of a real sound or outside stimulus. These false perceptions are the equivalent of an optical illusion: the listener hears either sounds which are not present in the stimulus, or sounds that should not be possible given the circumstance on how they were created.
Dub is an electronic musical style that grew out of reggae in the late 1960s and early 1970s. It is commonly considered a subgenre of reggae, though it has developed to extend beyond that style. Generally, dub consists of remixes of existing recordings created by significantly manipulating the original, usually through the removal of vocal parts, the application of studio effects such as echo and reverb, emphasis of the rhythm section, and the occasional dubbing of vocal or instrumental snippets from the original version or other works.
In music, groove is the sense of an effect ("feel") of changing pattern in a propulsive rhythm or sense of "swing". In jazz, it can be felt as a quality of persistently repeated rhythmic units, created by the interaction of the music played by a band's rhythm section. Groove is a significant feature of popular music, and can be found in many genres, including salsa, rock, soul, funk, and fusion.
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.
In musique concrete and electronic music theory the term sound object is used to refer to a primary unit of sonic material and often specifically refers to recorded sound rather than written music using manuscript or a score. It was coined by Pierre Schaeffer in his publication Traité des objets musicaux (1966).
Sound art is an artistic activity in which sound is utilized as a primary medium or material. Like many genres of contemporary art, sound art may be interdisciplinary in nature, or be used in hybrid forms. According to Brandon LaBelle, sound art as a practice "harnesses, describes, analyzes, performs, and interrogates the condition of sound and the process by which it operates."
Acousmatic music is a form of electroacoustic music that is specifically composed for presentation using speakers, as opposed to a live performance. It stems from a compositional tradition that dates back to the introduction of musique concrète in the late 1940s. Unlike musical works that are realised using sheet music exclusively, compositions that are purely acousmatic often exist solely as fixed media audio recordings.
Sound studies is an interdisciplinary field that to date has focused largely on the emergence of the concept of "sound" in Western modernity, with an emphasis on the development of sound reproduction technologies. The field first emerged in venues like the journal Social Studies of Science by scholars working in science and technology studies and communication studies; it has however greatly expanded and now includes a broad array of scholars working in music, anthropology, sound art, deaf studies, architecture, and many other fields besides. Important studies have focused on the idea of a "soundscape", architectural acoustics, nature sounds, the history of aurality in Western philosophy and nineteenth-century Colombia, Islamic approaches to listening, the voice, studies of deafness, loudness, and related topics. A foundational text is Jonathan Sterne's 2003 book "The Audible Past", though the field has retroactively taken as foundational two texts, Jacques Attali's Noise: The Political Economy of Music (1985) and R. Murray Schafer's The Tuning of the World (1977).
Chromesthesia or sound-to-color synesthesia is a type of synesthesia in which sound involuntarily evokes an experience of color, shape, and movement. Individuals with sound-color synesthesia are consciously aware of their synesthetic color associations/perceptions in daily life. Synesthetes that perceive color while listening to music experience the colors in addition to the normal auditory sensations. The synesthetic color experience supplements, but does not obscure real, modality-specific perceptions. As with other forms of synesthesia, individuals with sound-color synesthesia perceive it spontaneously, without effort, and as their normal realm of experience. Chromesthesia can be induced by different auditory experiences, such as music, phonemes, speech, and/or everyday sounds.
In physics, sound is a vibration that propagates as an acoustic wave, through a transmission medium such as a gas, liquid or solid. In human physiology and psychology, sound is the reception of such waves and their perception by the brain. Only acoustic waves that have frequencies lying between about 20 Hz and 20 kHz, the audio frequency range, elicit an auditory percept in humans. In air at atmospheric pressure, these represent sound waves with wavelengths of 17 meters (56 ft) to 1.7 centimeters (0.67 in). Sound waves above 20 kHz are known as ultrasound and are not audible to humans. Sound waves below 20 Hz are known as infrasound. Different animal species have varying hearing ranges.
Timbral listening is the process of actively listening to the timbral characteristics of sound.
Synesthesia or synaesthesia is a perceptual phenomenon in which stimulation of one sensory or cognitive pathway leads to involuntary experiences in a second sensory or cognitive pathway. People who report a lifelong history of such experiences are known as synesthetes. Awareness of synesthetic perceptions varies from person to person. In one common form of synesthesia, known as grapheme–color synesthesia or color–graphemic synesthesia, letters or numbers are perceived as inherently colored. In spatial-sequence, or number form synesthesia, numbers, months of the year, or days of the week elicit precise locations in space, or may appear as a three-dimensional map. Synesthetic associations can occur in any combination and any number of senses or cognitive pathways.
Psychoacoustics is the branch of psychophysics involving the scientific study of sound perception and audiology—how humans perceive various sounds. More specifically, it is the branch of science studying the psychological responses associated with sound. Psychoacoustics is an interdisciplinary field of many areas, including psychology, acoustics, electronic engineering, physics, biology, physiology, and computer science.
Sonic interaction design is the study and exploitation of sound as one of the principal channels conveying information, meaning, and aesthetic/emotional qualities in interactive contexts. Sonic interaction design is at the intersection of interaction design and sound and music computing. If interaction design is about designing objects people interact with, and such interactions are facilitated by computational means, in sonic interaction design, sound is mediating interaction either as a display of processes or as an input medium.
Ecomusicology is an area of study that explores the relationships between music or sound, and the natural environment. It is a study which encompasses a variety of academic disciplines including musicology, biology, ecology and anthropology. Ecomusicology combines these disciplines to explore how sound is produced by natural environments and, more broadly how cultural values and concerns about nature are expressed through sonic mediums. Ecomusicology explores the ways that music is composed to replicate natural imagery, as well as how sounds produced within the natural environment are used within musical composition. Ecological studies of sounds produced by animals within their habitat are also considered to be part of the field of ecomusicology. In the 21st century, studies within the field the ecomusicology have also become increasingly interested in the sustainability of music production and performance.
Sharawadgi or sharawaggi is a style of landscape gardening or architecture in which rigid lines and symmetry are avoided to give the scene an organic, naturalistic appearance. This was supposedly a concept in the Chinese garden, and starting with Sir William Temple's essay Upon the gardens of Epicurus, may have been influential in English landscape gardening in the 18th century. The reports from China of the Jesuit missionary, Father Attiret added to this. Sir William Temple first used the word "sharawadgi" in discussing the Chinese idea of beauty without order in garden design, in contrast to the straight lines, regularity, and symmetries then popular in the formal Baroque gardens of Europe, led by the French formal garden. The style indicates a certain irregularity in the design.
Sound maps are digital geographical maps that put emphasis on the sonic representation of a specific location. Sound maps are created by associating landmarks and soundscapes.
