研究概览
简要总结
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.

主要结局
Cochlear Implant: Signal to Noise Ratio (SNR) Threshold Obtained From IEEE (Speech Perception in Noise Test) Sentence in Noise Test.
时间窗: 12 minutes
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 directions * Ipsi: the same side * Front * Contra: Contralateral, from the opposite side of the implant Visits are flexible, based on participant preference and may be completed any time between enrollment and end of study. Testing takes about 12 minutes.
CI CROS: Signal to Noise Ratio (SNR) Threshold Obtained From IEEE (Speech Perception in Noise Test) Sentence in Noise Test.
时间窗: 12 minutes
The IEEE test allows a researcher to evaluate how well a subject understands sentences in noisy situations. Primary Outcome #2 will assess how well the listener can hear wearing his/her cochlear implant and a CROS (Contralateral Routing of Signals device). A CROS is a device on the opposite ear that sends the nose to the 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 directions * Ipsi: the same side * Front * Contra: Contralateral, from the opposite side of the implant Visits are flexible, based on participant preference and may be completed any time between enrollment and end of study. Testing takes about 12 minutes.
CI HA: Signal to Noise Ratio (SNR) Threshold Obtained From IEEE (Speech Perception in Noise Test) Sentence in Noise Test.
时间窗: 12 minutes
The IEEE test allows a researcher to evaluate how well a subject understands sentences in noisy situations. Primary Outcome #3 will assess how well the listener can hear wearing his/her cochlear implant and hearing aid. 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 directions * Ipsi: the same side * Front * Contra: Contralateral, from the opposite side of the implant Visits are flexible, based on participant preference and may be completed any time between enrollment and end of study. Testing takes about 12 minutes.
