PURPOSE: This review aimed at presenting the benefits regarding the speech perception in noise shown by children who wear hearing aid devices and/or cochlear implants with the Frequency Modulation (FM) System at school. RESEARCH STRATEGY: A bibliographic survey was conducted in an electronic database with standardized search until the year 2012, and a manual search was performed by using specific keywords. SELECTION CRITERIA: For the selection and evaluation of the scientific studies chosen in the search, criteria were established covering the following aspects: type of study, participants, adopted intervention, and evaluation of results. DATA ANALYSIS: The FM system was verified to improve speech perception and speech threshold in noise in all studies. RESULTS: Regarding the performance as to type, the best results were obtained when children used the personal FM system, followed by the table and the sound field systems. CONCLUSION: After extensive review of national and international literature, it was concluded that the studies indicate the need for further research concerning mainly the impact of the FM system on the school performance of children who have sensory devices coupled to the FM system. Findings in the literature with relation to the publications focused on speech perception in noise did not relate educational and auditory aspects.
