FIG. 2.
Free-field thresholds measured preoperatively and with the investigational device 6 months after surgery in patients with MHL or CHL (n = 23; A) and patients with SSD (n = 4; B), where error bars represent the standard deviation of the mean. Word recognition scores in quiet (n = 27; mean and 95% CIs; C) and SRTs in noise (n = 27; mean and 95% CIs; D), both measured preoperatively unaided and with the investigational device at 6 months. CHL indicates conductive hearing loss; CI, confidence interval; MHL, mixed hearing loss; SRTs, speech reception thresholds.
