Abstract: According to structure and function of auditory cognitive neural information processing,a new auditory saliency computing model based on mechanisms of selective attention cognitive neural was proposed in this paper,and referring to principle of image processing,algorithms of auditory saliency were presented．This model simulates both the bottom-up and top-down human auditory attention mechanism．In selective attention saliency extraction and background noise restrain,the model has achieved satisfactory results in simulation and natural audio experiments．
