"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."

"Acoustic Subtraction is a sound experiment which involves filling a public space with white noise and then rapidly pulling the plug. 20 minutes of white noise followed by 20 minutes of silence."

"No field of study based on sensory experience seems to be overburdened by terminology to the same extent as that dealing with sound and hearing. The visual sense, of course, has received as much attention as the auditory from physics, psychology, neurophysiology, and the visual arts, which have all contributed terminology and jargon alike, but a great deal of it seems to have entered the common vocabulary already, and at least the general notions involved are seldom foreign to the average citizen or student. Terms such as perspective, foreground, background, colour, spectrum, shadow, focus, image, reflection, transparent, translucent and the wealth of descriptive visual terms, not to mention common visual impairments and the complexity of visual language found in contemporary cinema and photography - all of these have found public familiarity in a way that it is hard to imagine their sonic counterparts ever matching. Almost every school child knows what white light is, and how it is composed, but would he know what white noise is, even though the likelihood of it having an adverse effect on him is far greater? The ability to perceive three-dimensional visual perspective when projected onto a two-dimensional surface, by no means a simple achievement given the lateness of its appearance in our civilization, is irrevocably ingrained in the child's perceptual habits at an early age, and yet the ability to distinguish acoustic parameters, or experience subtle nuances of timbre (supposing he knows what timbre, the sonic equivalent of colour, is) may never be among his perceptual skills."

"Acoustic Subtractions are events in public space: Twenty minutes of white noise followed by twenty minutes of "silence." "

"Some of the hottest tracks on digital playlists: sounds of an oscillating fan, a waterfall and crickets. White noise and other soothing sounds, once mainly played on machines to aid nighttime sleep, are increasingly helping make daytime hours more serene. When played through headphones, the sounds help people tune out chatty co-workers, pounding jackhammers and the dentist's drill. "

"Jesper Norda created the sound installation The Centre of Silence for the Kalmar Konstmuseum. The installation consists of an empty room and sound, nothing else. A voice describes the space and the movement of air molecules in the room. In between the pieces of text the listener is treated to silence, a sine wave and white noise. "
