Background and Aim: There are four fundamental processes of attention: working memory, top-down sensitivity control, competitive selection, and automatic bottom-up filtering for salient stimuli. Each process makes an essential contribution to attention. Voluntary control operates on the first three processes in a recurrent loop. We reviewed comprehensive researches, theories, mechanisms, and central nervous system functions of auditory attention.

Methods: In this study, publications on auditory attention from 1953 to 2012 in PubMed, Scopus, ProQuest, Iran Medex, and Goole scholar were reviewed. Keywords were auditory attention and related words.

Conclusion: In general, auditory attention plays an important role in auditory processing and modulates this process from cochlea to auditory cortex through its four primary components.
