Purpose: The present pilot study aimed to provide estimates of the feasibility and efficacy of a remote microphone (RM) system as an augmentative intervention to improve the functional listening performance of preschool children with autism spectrum disorder (ASD) and language disorder. Method: Eight children with ASD and language disorder participated. Efficacy of the RM system was determined by evaluating participants' functional listening performance, as measured by an observational measure in RM-off and RM-on conditions. Responses were evaluated at the individual level using an alternating conditions design. Results: Adequate feasibility was demonstrated as all participants were able to complete tasks in the RM-on condition. A subset of participants showed significant improvements in their functional listening performance in the RM-on condition, as demonstrated by visual inspection and effect sizes (nonoverlapping data points and percentage of data points exceeding the mean), indicating that there may be important sources of individual differences in responses to RM use in children with ASD. Conclusion: The results of this pilot study provide support for future research on RM systems to target functional listening performance in children with ASD and language disorder.
