This study explored: (1) the benefits of an FM system in real-world environments from the perspective of adults with coch-lear implants, and (2) the factors and barriers to using an FM system with a cochlear implant. Using a qualitative research design, 14 adults with unilateral cochlear implants recorded their experiences during a two-month trial period with a personal FM system and responded to a questionnaire at the end of the trial. A detailed analysis of 169 journal entries (230 hours of FM use) permitted a description of the benefits and negative aspects associated with FM use in everyday listening environments. The primary benefits were related to improved access to and quality of sound, improved distance listening, ease of listening, and better social integration. Negative perceptions were associated with the equipment both with regard to physical aspects and adjustments. In addition, technical, individual, social, and environmental factors were identified that can influence the user's decision to use the FM device. Questionnaire responses indicated that the majority of individuals rated the FM system as somewhat or very helpful. The findings suggest that FM systems can improve communication in everyday listening environments for some adults with cochlear implants.
