Alison King Principal Audiologist, Paediatric Services Presentation to Audiology Australia National Conference 2010 FM system usage and benefit for children and young adults
Child & Young Adult FM Survey – Oct. 2009 Mailed to all clients <21 who had an FM system listed as a current device (n=6248) 1337 respondents (21.4%) – 11 (0.8%) Indigenous 72.2% had FM input to one ear; 27.8% to both ears FM styles used with hearing aid and/or implant – Ear level (DAI) = 86% – Induction loop = 8.7% 18% of implantees vs 6% of HA users – Body Level 4.8% 87% satisfied or very satisfied with their FM system.
Usage Patterns 85.8% used their FM for at least a few lessons per week in an educational setting – 58.6% “almost every lesson” – 38.6% used the FM in other situations. 17% have to listen to >1 teacher during class on most days 16% use in a room with Sound field system most days 14.2% NEVER used their FM system. – Most common reasons: “I don’t think I need it” or “I don’t like to wear it” – Not related to degree hearing loss 14.5% (164) had a transmitter that enabled the user to change microphone settings – 15.9% (30) of these changed setting in different environments.
Which factors were related to FM benefit? Overall benefit score derived from sum of scores across situations Age – Younger children derived more benefit than older children Severity of hearing loss – The more severe the hearing loss, the greater the reported benefit Frequency of technical problems – Less benefit reported if respondent answered “often” or “all the time” for problems with distortion/interference, transmission range or intermittency.
Which factors were not related to FM benefit? Gender The Hearing Aid/Cochlear implant fitting configuration Unilateral vs bilateral FM input
Summary FM satisfaction rates were high. FM systems are most commonly used in educational settings, but deliver significant benefit when used in other situations. – Encourage wider application of FM systems 16-17% of respondents are in educational settings that pose additional complexities (multi-teacher, SFAS) – Challenges for instruction & support
Summary Technical problems affect benefit of FMs – Implications for Parent/teacher/student education Support & follow up by family audiologist, educational audiologist and visiting teachers.
