Objectives: For children with hearing loss, remote microphone (RM) technology can significantly improve access to speech in environments with poor signal-to-noise ratios (SNRs), such as classrooms. Yet, this has never been studied in bone conduction device (BCD) users, a common treatment for children with irresolvable conductive hearing loss resulting from anatomical malformations of the outer ear. The objective of this study was to investigate the benefits of RM technology on speech perception in noise in pediatric BCD users with Microtia/Atresia. A secondary aim was to assess parent and child perceptions of RM technology before and after exposure to RM technology. Methods: Participants included 10 pediatric bone conduction implant users with unilateral conductive hearing loss ages 7–17 years, and their guardians. Speech perception in noise for soft and moderate inputs was assessed with and without RM technology. Guardians actively observed the child's hearing performance with and without the RM and were asked to complete a questionnaire assessing their perceptions about their child's performance. Children were also administered the questionnaire prior to and immediately following exposure to the RM technology. Results: Participants showed improved speech understanding in noise for both soft and moderate speech inputs when using the RM with their BCD compared to their BCD alone. Questionnaire results indicated good parent-child agreement. Further, significant improvements were reported for child understanding speech, parent hearing domains after exposure to the RM. No significant differences were noted for ease of use/likability. Conclusions: Significant hearing in noise benefits were observed with RM technology for children using BCDs. Consistent with objective findings, children reported improved speech understanding with the RM. Improved parental perceptions of hearing benefit following exposure to the RM suggests that active participation may serve as an effective strategy to help improve parent understanding of the benefits of RM technology for their child.
