Study Summary
Speech understanding in noise remains the greatest challenge for people using cochlear implants, particularly when the speech of interest comes from the side of the head opposite to the implant. Recent findings in hearing technology allow for people to either use a hearing aid or a Contralateral Routing of Signal (CROS) device on the non-implanted ear. Differences in speech understanding may result depending on the device chosen by a person, and these differences may be measureable through speech discrimination measurement methods. This study intends to determine whether or not a CROS device improves speech perception in noise when the source of the speech of interest originates from the side of the head opposite to the implant.
Primary Outcome
The IEEE test allows a researcher to evaluate how well a subject understands sentences in noisy situations. Primary Outcome #1 will assess how well the listener can hear with his/her cochlear implant. The listener will be tested without a contralateral device versus also wearing a contralateral device while listening to sentences coming from various directions along with competing noise coming from various directions. The directions of the sentences or noise are as follows: * Omni: from all dir
Interventions
- DEVICE Hearing Aid
- DEVICE CROS
- OTHER Cochlear Implant Alone
