Rustle noise is noise consisting of aperiodic pulses characterized by the average time between those pulses (such as the mean time interval between clicks of a Geiger counter), known as rustle time (Schouten ?). Rustle time is determined by the fineness of sand, seeds, or shot in rattles, contributes heavily to the sound of sizzle cymbals, drum snares, drum rolls, and string drums, and makes subtle differences in string instrument sounds. Rustle time in strings is affected by different weights and widths of bows and by types of hair and rosin in strings. The concept is also applicable to flutter-tonguing, brass and woodwind growls, resonated vocal fry in woodwinds, and eructation sounds in some woodwinds. Robert Erickson suggests the exploration of accelerando-ritardando scales producible on some acoustic instruments and further variations in rustle noise "because this apparently minor aspect of musical sounds has a disproportionately large importance for higher levels--textures, ensemble timbres, contrasts between music events." (Erickson 1975, p.71-72)

Famous quotes containing the words rustle and/or noise:
“Every day or two I strolled to the village to hear some of the gossip which is incessantly going on there, circulating either from mouth to mouth, or from newspaper to newspaper, and which, taken in homoeopathic doses, was really as refreshing in its way as the rustle of leaves and the peeping of frogs.”
—Henry David Thoreau (1817–1862)
“But what it was, alas, I cannot tell,
Because of it I had no perfect view;
But as it was, by guess, I wish it well
And will until I see the same anew.
Shadow, or she, or both, or choose you whither:
Blest be the thing that brought the shadow hither.”
—Unknown. I Heard a Noise and Wishèd for a Sight (l. 13–18)
