Great visualization about how speakers work. "Speakers (also called loudspeakers) push and pull surrounding air molecules in waves that the human ear interprets as sound. You could even say that hearing is movement detection. So what makes a speaker travel back and forth at just the right rate and distance, and how does that make sound?"

"This paper will explore how the practice of soundwalking can be a tool for memory retrieval. I ask: How are memories created and remembered in the mind and felt within the body? What happens to our perception of self, home, and knowing as we move through spaces and places of significance? "

"My research is also experimenting with new immersive technology in the areas of vibrotactile experiences, gesture recognition devices and sensor technology that translates body movement into digitally generated sound and image. Each of these technologies has initially been developed to enhance the sensory experiences of those with sensory loss, mental illness or individuals with disabilities."

"Time and Tide Bell" is a permanent installation, existing of 12 bells around the U.K. in several very different locations, rung by the sea at high tide. The rise of the water at high tide moves the clapper to strike the bell. Played by the movement of the waves, the bell creates a varying, gentle musical pattern. As the effect of global warming increases, the periods of bell strikes will become more and more frequent, and as the bell becomes submerged in the rising water the pitch will vary."

"For Hong Kong artist Samson Young, however, war sounds less obviously martial; indeed, it's pretty random. It's calm, somewhat foreboding - human, organic, often silent but with bursts of technological noise. And most importantly for Young, war sounds musical. Visitors to the artist's current exhibition at Team Gallery, Pastoral Music, see him sitting in the center of the room wearing fatigues, staring into an obsolete television monitor, surrounded by a surfeit of sound-making devices, some traditionally musical, like a contact mic hooked to a bass drum, and some definitely not, like soil, a room fan, Corn Flakes. What's going on exactly? The unconventional musical scores hanging - or, in some cases, drawn directly - on the walls suggest that Young's restrained movement amid the mess of sound-producing gadgets must constitute a musical performance."

"Given light, space, electricity, and a stack of discarded electronics, Thessia Machado will make music. For more than a decade, the sound artist has been building her own instruments with found and modified parts-old speakers, circuit boards, fax machines-intent on broadening the dimensions of sound and sound-making. Unlike traditional instruments, Machado's creations and installations generate sounds triggered by atmospheric factors such as light, movement, and electromagnetic waves. They harness and marshal the ambience, audibly expressing their environments. "These sounds that [were] not there, are now there," she says. And sound, she adds, is "basically air that's organized.""

"Bodyscape is inspired by the body of a dancer as sonic source. The information is taken via biosensors and microphones, which record movements and events generated by the body. In this ecosystem, the dancer produces sounds, mainly inaudible, which are then amplified and send back to the performance space, where the dancer interact with them as biofeedback. The site-specificity of the work relates to the spatial considerations and resonances. Field recordings were collected at the border of Botswana and South Africa. L'épidemie virale en Afrique du Sud, a text from the Swiss writer Friedrich Dürrenmatt, informed the journey. The text describes a virus transforming white persons into black persons. A text about privileges."

"It is common knowledge that babies and small children fall asleep in the car quite easily. This could be a few things, the muffled engine noise, the slight vibration of the car, a regulated temperature. Furthermore it could be a conditioned response: when kids are put in a seat and strapped in, they can't really move around much and are kind of forced to relax. They have probably slept in the car before so are conditioned to do it again. Using this knowledge, Ford is promoting it's new vehicle range with "Max Motor Dreams", a baby crib that reproduces the sounds, movement and light of a parent's car. Parents are even able to use an app to collect data from routes and replay it in the crib at home."

"Silenced voices of disappeared dissidents and migrant slaves. Melodies lost to the violence of empire. Vanished monuments marking anti-colonial choruses. Hidden, transgressive dances of migrant domestic workers. Inaudible and obscured, these sounds and movements haunt Hong-Kai Wang's work. Rather than erecting monuments to these pasts, Wang uses listening, sounding, and singing as conduits to these lost or absent acts across temporal and geopolitical distances. This practice, situated around sound both real and imagined, might be described as anti-monumental."

"NIC Kay's #blackpeopledancingontheinternet explores ways that Black online communities have engaged in the transcultural exchange of dance, movement, and music, claiming and maneuvering the internet as a space for visible, culturally coded play, political organization, and innovation."

We Come From Your Future is a sound investigation into the future of anti-racism in the UK. It asks how the public discourse on ethnicotherness, diversity, and multiculturalism may contribute to the very conditions of racism? How has the erasure of terms like anti-racism, racist violence, and justice from the official bureaucratic language actually worked to both conceal and foment new convergences of racial tension? How has the composition and re-composition of migration in the UK contributed to new lines of anti-racist experience and opened up to new fields of struggle? What are the obstacles for a re-constitution of an anti-racist movement?

"As cars become more and more silent, the question "what should cars sound like?" becomes more and more relevant. "

NASA's Jupiter-bound Juno spacecraft has entered the planet's magnetosphere, where the movement of particles in space is controlled by what's going on inside Jupiter. "We've just crossed the boundary into Jupiter's home turf," said Juno Principal Investigator Scott Bolton of Southwest Research Institute, San Antonio. "We're closing in fast on the planet itself and already gaining valuable data."

"Electronic music has been around for about a century, and women (however ignored) have been a part of the movement from the beginning. Sisters With Transistors - a film with an excellent title - tells the story of electronic music's female pioneers, starting with the Lithuanian Clara Rockmore, who performed solo in the 1920s at the New York Philharmonic with a theremin, one of the very first electronic instruments. "

Locative audio experience at the Brooklyn Museum. "In times of global surveillance scandals, purported no-spy agreements and increasing numbers of whistleblower platforms, with Top Secret International (State 1) Rimini Protokoll enter the global web of state secrets and secret services - the state within the state. In the first part of the tetralogy, which will deal with post-democratic phenomena for two years, an algorithm and a smartphone turn audience members into inconspicuous agents. Playing the role of journalists, visitors will listen in on investigations by foreign intelligence services, put themselves in the shoes of a whistleblower or be fitted with a legend. Between statues in a museum, they can hardly be singled out from other museum visitors. Using subtle gestures, purposeful movements, they access files and archives that open gradually; biographies from politics, journalism and espionage, globally active individuals with security clearance and activists mark out the playing field. The audience members watch and track one another, contact one another, form coalitions or refuse to connect."

"framework began broadcasting in june, 2002 on the newly reformed resonance 104.4fm in london. the show now airs on twelve radio stations around the world, with regular new additions to its broadcast family, and streams and podcasts here on its own website. framework is consecrated to field recording and its use in composition, and began broadcasting at a time when a new community of sound artists with a special interest in found sound was developing, a community spread across the globe that, thanks to the internet, was no longer limited to a specific geography. framework sees itself as an outlet for this ever-growing and developing community, a folk-tool in a new folk movement, a community driven exchange point for creators and listeners alike. framework's goal is to present not only the extremely diverse sound environments of our world, but also the extremely diverse work that is being produced by the artists who choose to use these environments as their sonic sources. we hope to ask this question: is 'field recording' a style, or a genre, or is it in fact as uncontrollable and undefinable an instrument or tool as any, that may be interpreted, manipulated, and appropriated by anyone with a microphone and an idea? these works are its definition, and not vice versa. "

Infrasonica is a digital platform of non-Western cultures. We record, analyze and debate the eeriness of sound and its auras, linked to the world with the audible, the hidden and the sensitive. Infrasonic waves operate at a frequency that is undetectable by human ears even though they are often generated by massive ecological phenomena, such as the movement of tectonic plates or the deep currents of the ocean. Infrasonica aims to be a catalyst for those vibrations. The platform includes archives of experimental sound and visual artists, as well as theoretical musings on contemporary critical thought. By relying on a borderless network of collaborators, Infrasonica blends essays, conversations and speculative works that encourage critical curatorial and research projects.

In the decades following World War II, the musical score emerged as a unique and powerful medium for experimental art. A new movement of visual artists, composers, poets, and performers reimagined the score-traditionally defined as the written representation of a musical composition-as a tool for structuring experimentation in the nascent fields of performance art, conceptualism, and intermedia. They drew inspiration from unconventional musical notations devised in the early to mid-1950s by the composers Earle Brown, John Cage, and Morton Feldman. The new movement's use of experimental scores spread during the 1960s through publications, festivals, concerts, classrooms, networked correspondence, exhibitions, happenings, and a renewed awareness of score-like antecedents in the charts, diagrams, sketches, and written instructions of earlier avant-gardes, from Dada and Surrealism to the Bauhaus. By the later years of the 1960s, diverse communities of artists, musicians, poets, and dancers had transformed the possibilities of the score into an ever-expanding universe of textual, symbolic, and graphic marks. They used experimental scores to stage a multitude of practices that dismantled and recast the traditional boundaries of artistic media.

"When did you last use radio technology? If you're straining to remember when you last turned on the AM/FM radio broadcast receiver in your car, you've probably gone too far back. Although it might not come to mind when we think about radio in the digital media era, things like GPS, wireless computer networks, and even our mobile phones use radio waves.  Far from being outdated, this century-old technology is still integral to much of what we do. "On the one hand, it's very ambient. We don't notice it," says Rick Prelinger, an archivist and professor emerit of film and digital media at the University of California, Santa Cruz. "But radio is also deeply engaged with the world." "

"You can look across a vast expanse of ice, all white and blue and cold, and see nothing. The lead is choked with pack ice or sealed over with newly formed ice, and there is no movement or sound. With few birds, no whales and no bears, one might mistake the Arctic for a desert. But if you go down to the ice edge, pick a hole in the new ice deep enough to reach water and drop in a hydrophone (an underwater microphone), the cacophony is astonishing. "
