Figure 2:

Speech recognition as a function of perceived benefit, shown separately for word recognition in quiet with the CI alone (top row) and sentence recognition in spatially-separated noise with the CI and the acoustic-hearing ear (bottom). Subjects are adults with UHL or AHL who underwent testing at the preoperative, 1-month, and 12-month intervals. Speech recognition scores are reported in rationalized arcsine units (RAUs). Higher values indicate greater perceived benefit and better speech recognition. The solid line indicates significant correlation between sentence recognition in spatially-separated noise (SoNcontra) and perceived listening effort at the 12-month interval for the UHL cohort.
