Design outcomes

Primary

Measure	Time frame
Speech Reception Threshold (SRT) in decibel.	—

Secondary

Measure	Time frame
Subject characteristics that could possibly influence the performance, for example residual hearing, duration of deafness, type of implant, electrode position in cochlea, duration of implantation, clinical Consonant-Vowel-Consonant (CVC) scores, demographics, participant ratings of sound perception with the loudness balancing feature of CROS device, and percentage of words correct in a sentence or SRTs with the CROS feature.	—
