"Untitled V is a sound sculpture that consists of miniature speakers acoustically activated by a motor driven mechanism. A nylon thread is fastened through a hole at the center of the membrane; the end of the nylon thread is loosely secured to a motor turned rosined wheel to produce friction. Sound is produced by the action of the rim of the rotating wheel rubbing the thread as the wheel is turned. The two surfaces alternating between sticking to each other and sliding over each other, with a corresponding change in the force of friction. The motor speed is reduced at the lowest speed. The slow turn of the wheel creates changes in the tension of the thread, resulting as sounds (crackling impulse) in the membrane of the speaker. Untitled V creates a very quiet listening experience.

"It's a sonic phenomenon that occurs in only certain pockets of desert around the world. The sound of sand grains shuffling down hot slopes that can recall the angry buzz of bees or the deep, groaning thrums of a didgeridoo group. Scientists refer to these shifting dunes as "singing" or "booming" sands, which for centuries mystified explorers from Charles Darwin to Marco Polo. We know now that these strange sounds are caused by the vibrations of grains avalanching, at relatively slow speeds, down dunes, and that the grain size and speed influence the notes of these curious hums of nature."

"The first audio recordings on Mars reveal a quiet planet with occasional gusts of wind where two different speeds of sound would have a strange delayed effect on hearing, scientists said Friday."

"Nature has published a new article about the acoustic environment of Mars, called "In situ recording of Mars soundscape", from a long term research done by a vast group of astrophysicists and space explorers, primarily based on recordings taken by NASA's Perseverance rover, which has been on the planet since February 2021 and has discovered that the "red planet" has two different speeds of sound, as well as some special acoustic proprieties. "

"86 people lined up in a 1.7 km straight line to conduct an experiment to test the speed at which soudns travel between cymbals and people."

"Dr. William W.H. 'Bill' Gunn (1913-1984) was a field recordist, conservationist and early populariser of nature sounds, recording landscapes in the Galapagos Islands, East Africa, Sri Lanka and locations across Canada including its Far North. A key technique in his practice and teaching was sound microscopy-slowing down the playback of his recordings to reveal details unable to be perceived at full speed. This presentation considers Gunn's slowing in relation to a range of contemporaneous practices of slowing (in speech therapy, music composition, etc.) as well as the context of his field and the 'slow violence' of ecological devastation. As listeners, we meditate on the wonder elicited from Gunn's human audience but also the absences, extractions and exclusions entwined with Gunn's exploration of musical microcosms."

"We created a device that visualizes the speed at which sound travels through the air, 340 meters per second." "

"Sound Waves and Music - Lesson 2 - Sound Properties and Their Perception"

THE BOUNCY BEEPS of Pac-Man. The percussive build-up in Legend of Zelda. The effusive gibberish of The Sims. The sounds in videogames tell us to speed up, start over, and of course, to keep playing. But how does one set of beeps so effectively tell you you've gained power, while another indicates your character has died? And how, exactly, does someone create the sound of the Dark Knight punching the Joker in the face? The answer: Genius sound design.

"The noise sounds like wind, or heavy rain, or the steady hum of an airline jet. It sounds like water rushing somewhere in the distance, like a gentle fan ruffling currents of cool air. It's soothing, steady, slightly rumbly. Welcome to the cult of BROWN NOISE, a sometimes hazily-defined category of neutral, dense sound that contains every frequency our ears can detect. Brown noise is like white noise but has a lower, deeper quality. It gained a fervent following over the summer, picking up speed in online A.D.H.D. communities, where people made videos of their reactions to hearing it for the first time. Many said it allowed their brains to feel calm, freed from an internal monologue. Some invited their viewers to try it too, and commenters chimed in, claiming that brown noise was not only a tool to help them focus, but could relieve stress and soothe them to sleep."

"Central to Doug Aitken's "100 YRS" exhibition is a new "Sonic Fountain," in which water drips from 5 rods suspended from the ceiling, falling into a concrete crater dug out of the gallery floor. The flow of water itself is controlled so as to create specific rhythmic patterns that will morph, collapse and overlap in shifting combinations of speed and volume, lending the physical phenomenon the variable symphonic structure of song. The water itself appears milky white, as if imbued and chemically altered by its aural properties, a basic substance turned supernatural. The amplified sound of droplets conjures the arrhythmia of breathing, and along with the pool's primordial glow, the fountain creates its own sonic system of tracking time."

"The "Sonògraf" is an electronic audiovisual instrument. Thought as a music learning tool for primary schools, it allows the drawing to be transformed into music, turning gestural strokes and geometric figures into electronic sounds. A set of buttons and potentiometers allow live manipulation of the "sonification" characteristics of the drawing, making it possible to speed up, slow down or pause the resulting music, as well as decide its scales and tonalities."
