The auditory system can discard uninformative noise and use only informative samples for detection
Evidence
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
