The scalp-recorded auditory steady-state response (ASSR) is a periodically evoked potential in response to the stimulation with the acoustical property in the same period. The ASSR can be readily induced in comparison with transient responses for specific conditions. The clinical utility of ASSR may be unjustified for the ambiguity of the genesis. With the advance of relevant research, it is considered that the main generation hypotheses of the ASSR are conceived to be pertinent with the linear superposition or neural entrainment mechanism. Based on current findings and our contributions in this field, we introduce recent progresses of the two mechanisms with comments, and suggest the benefit of the rapid stimulation technology in this regard.
听觉稳态反应（ASSR）是某种周期性连续刺激模式下，在头皮上记录的听觉及相关神经活动信息。在特定条件下，ASSR 反应比瞬态反应更易引出，具有独特的临床应用价值，但目前 ASSR 的产生机制尚存争议，影响相关应用的推广和深化。随着新的处理技术和研究成果的出现，现在认为 ASSR 主要和线性叠加以及频率挟带理论有关。根据当前研究进展和我们的工作贡献，本文特别对此加以梳理和评论，指出高刺激率瞬态信号重建技术可望促进稳态反应产生机制的研究。.
