Figure 8
Changes in speech perception asymmetry in quiet. Asymmetry in speech perception tested in quiet increases as a function of (a) delay to bilateral implantation in sequential bilateral cochlear implant (CI) users, and (b) unaided pure-tone average (PTA) of hearing thresholds for 0.5, 1, and 2 kHz in the non-implanted ear with the hearing aid (HA) of bimodal users. The dotted vertical line in (b) indicates a severe-to-profound hearing loss (80 dB HL). Blue shaded regions indicate ±1 SD asymmetry of the simultaneous group for comparison. CI = cochlear implant; RAU = rationalized arcsine unit.
