Natural Sounds Stimulus Set

The sound set includes 165 natural sounds, each 2-seconds in duration. The sounds were intended to include many of the sounds people commonly hear in their daily life.

Source Repetition Stimuli

We used a simple generative model to synthesize novel sounds with naturalistic properties. We found that such sounds could be segregated and identified if they occurred more than once across different mixtures, even when the same sounds were impossible to segregate in single mixtures.
