Brief Summary

Review the sponsor-provided synopsis that highlights what the study is about and why it is being conducted.

The purpose of this investigation is to evaluate objective outcomes in pediatric bone conduction hearing device (often termed "BAHA") users with and without remote microphone (RM) technology. In this study, two remote microphone technologies will be evaluated to determine benefit in speech understanding in noise.

Study Groups

Review each arm or cohort in the study, along with the interventions and objectives associated with them.

Remote Microphone (RM) Technology Group

The RM technology group will limited to the pediatrics participants.

Participants will be tested separately on the three following conditions:

1. Bone Conduction Device (BAHA) only
2. BAHA + Wireless Audio-Streaming Accessory
3. BAHA + Digital Adaptive RM System

Group Type EXPERIMENTAL

BAHA

Intervention Type DEVICE

Participant's pediatric bone conduction hearing device.

Wireless Audio Streaming Accessory

Intervention Type DEVICE

Cochlear Corporation's Mini Microphone 2+ Wireless Audio Streaming Accessory is an accessory used to transmit speech and sound. It consists of a microphone and a transmitter that transfers the signal to a receiver that's connected to a hearing device.

Digital Adaptive RM System

Intervention Type DEVICE

Sonova's Roger Digital Adaptive RM system is an accessory which can be connected to a compatible hearing aid. It offers an external microphone which streams signals directly to the connected hearing aid.

Normal Hearing Controls

The normal hearing controls will be limited to 15 adults.

Participants will be tested separately on the six following conditions:

1. Unaided
2. Unilateral hearing aid with contralateral plug.
3. Unilateral hearing aid + Digital Adaptive RM System (using Rogerâ„¢, Sonova)
4. Bone Conduction Device (BAHA) only
5. BAHA + Wireless Audio-Streaming Accessory
6. BAHA + Digital Adaptive RM System
