Evaluation of Speech-in-noise Performance in Cochlear Implant Recipients With a CROS Device on the Contralateral Ear

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.
