Abstract:
The phenomenon that the listener's reception,perception,and understanding of a sound are dis-turbed by an irrelevant sound is called the auditory masking effect.In the auditory masking effect,the human audi-tory nervous system is able to screen and extract target sounds from different sound sources based on different cues,and filter out unwanted masked sounds.The auditory masking effect is not a simple processing from separation to integration however it is,with a complex internal mechanism.Under energetic masking,acoustic information such as frequency and intensity of target and masher generates coding competition in the auditory periphery.Under infor-mational masking,target sound and masher competes with perceptive and cognitive information in the auditory cen-ter.Informational masking is the focus of masking research,but its mechanism is still controversial.This study studies the neural mechanism of informational masking effect from three factors,including similarity,uncertainty and intelligibility.
