Randomly timed tones model how new sound sources appear in a natural scene

Evidence

The stimulus of the present paradigm can be considered a stochastic version of the appearance or increase in loudness of a sound source within a natural auditory scene. Its design is a compromise between complexity of the spectrotemporal structure and simplicity in specification since the parameter-space is reduced to a minimum and parameters are straightforward to interpret. — Dijk, Pim van, Physiology, Psychoacoustics and…, 3343
