Auditory detection of near-threshold sounds depends on the phase of ongoing brain oscillations.

Evidence

Based on magnetoencephalography findings from a similar paradigm, Elhilali et al. ( 2009 ) proposed that the perceptual segregation of the modulated target from the distractors arises from temporal coherence of cortical activity patterns with the target. Whether tACS phase modulates this temporal coherence and therewith the segregability of the target remains to be shown; the preliminary data presented here indicate a trend toward a possible effect of 4-Hz tACS phase, as in experiment 1. — Dijk, Pim van, Physiology, Psychoacoustics and…, 4768 (#expands, via linked claim)

In developing the multiple looks hypothesis, Viemeister and Wakefield (1991) argued that if a stimulus contained uninformative snapshots, the energy detector would integrate them and degrade performance. However, the multiple looks mechanism would discard those uninformative pieces and use only the informative snapshots for detection. — Jennifer Lentz, Psychoacoustics- Perception of Normal…, 1066 (#qualifies, via linked claim)
