Use of RM Technology in Pediatric BAI Recipients

Study Overview
=================
Brief Summary
-----------------
The purpose of this research study is to learn about the hearing outcomes of children with conductive hearing loss who are treated with bone conductive devices and their outcomes with remote microphone technology.

Detailed Description
-----------------
The purpose of this research study is to learn about the hearing outcomes of children with unilateral conductive hearing loss who are treated with bone conductive devices and their outcomes with remote microphone technology. It has been shown that the use of intervention (hearing aids, cochlear implants, bone conduction devices) alone does not alleviate the difficulties children with hearing loss encounter in noisy environments such as a classroom or restaurant. One of the most common methods to help children hear better in these types of environments is the use of a personal remote microphone (RM) system. This study will evaluate how much benefit children are getting from their bone conduction device alone compared to the bone conduction device with a personal RM system.

Arms and Interventions

| Participant Group/Arm | Intervention/Treatment |
| --- | --- |
| Pediatric Group<br>Children with unilateral conductive hearing loss who are treated with bone conductive devices | Device: Personal remote microphone (RM) system<br>* Speech perception in noise performance will be evaluated in the unaided, bone conduction device (BAHA) aided, and bone conduction device (BAHA) + RM conditions. All test measures are non-experimental and commercially available.<br>Other: Subjective Questionnaire<br>* These subjective questionnaires will be given pre- and post-evaluation to both the subject and their guardian in order to determine the impact of RM on subject and guardian perceptions of listening in noise.<br>|
| Parent/Guardian Group<br>The parent or guardian of a child with unilateral conductive hearing loss who are treated with bone conductive devices | Other: Subjective Questionnaire<br>* These subjective questionnaires will be given pre- and post-evaluation to both the subject and their guardian in order to determine the impact of RM on subject and guardian perceptions of listening in noise.<br>|

Primary Outcome Measures

| Outcome Measure | Measure Description | Time Frame |
| --- | --- | --- |
| Speech Understanding in Noise | Investigate benefit of remote microphone (RM) for listening in noise in children with bone conduction hearing devices by calculating SNR loss | 40 minutes | 
| Parent and Child Perception of Hearing Loss Questionnaire | Determine the parent and child perception of the hearing loss and its impact pre- and post-evaluation using a subjective questionnaire created to further understand the child and parent's perception of their disability. | 20 minutes |
