Many definitions of selective attention tend to reference two components: a facilitatory mechanism that enhances the signal of interest, and an inhibitory mechanism that suppresses irrelevant and potentially distracting signals. These mechanisms have been studied extensively in vision, but less is known about their operation in audition. The present investigation tested whether suppression in auditory selective attention is sensitive to statistical regularities in complex scenes, which was shown in recent work in vision (Wang & Theeuwes, 2018). Participants listened to complex scenes consisting of several voices saying series of numbers and a distracting environmental noise. There were two possible distracting noises, one of which occurred much more frequently (70%) than the other (30%). One voice on each trial was a gender singleton, and participants were instructed to find that voice and report whether it was saying even or odd numbers. If suppression is an active component of auditory selective attention, it should reduce the influence of the distracting noise that occurs more frequently. Results revealed significantly faster RTs when the high-probability distracting noise was in the scene relative to when the low-probability distracting noise was in the scene, suggesting that participants used the frequency of the distractor across trials to aid performance. This result demonstrates that suppression mitigates the detrimental influence of a frequently occurring distracting sound.
