The idea to
"Record 8 seconds of white noise in your own personal style" comes to the Disquiet Junto via
Taylor Swift, who was credited with an accidental eight-second noisefest on her recent album.
My interpretation is a simple vocal rendition of white noise. I'd also considered collecting examples of white noise from my day, like the water sizzling when the percolator boils over or the sausages frying on the barbecue.
