A minimal tone cloud can isolate statistical predictability as the sole cue

Evidence

To achieve precise parameter control, we designed a minimal sound texture—a modified cloud of tones—which retains the central property of auditory textures: solely statistical predictability. Listeners had to rapidly detect a change in the frequency marginal probability of the tone cloud occurring at a random time. — Dijk, Pim van, Physiology, Psychoacoustics and…, 3282
