Much is still needed to be discovered by the neuroscience in relation to the consciousness regarding cognitive processes and the auditive perception in coma. Thus, this study is a bibliographic review on the auditive perception of patients in coma and shows its relevance to explain and identify evidence. To identify, in the publications found, the gaps, consistencies and inconsistencies on this subject. This study consists of a bibliographical survey based on LILACS and PUBMED database. Ten articles were selected about the subject, none of them are national publications. Most of the selected studies were published within the period of 1971-1995 (80%), by the United States (70%), as longitudinal research (50%) or study of case (30%); the sample in general varied between 1 and 5 (70%), the majority used music (80%); the EEG (60%) and behavior observation (50%) were the most used measuring ways of the responses to the stimulus. The procedures were varied, however most of the studies, show that there is an auditory perception in patients with coma.
