APHAB produces a global score and scores for four subscales: Ease of Communication, Reverberation, Background Noise, and Aversiveness. Global score is the average of all subscales. All scales range from 0-100%, where 0% indicates no problem and 100% indicates always problem. A decrease in the APHAB values indicates an improvement. The difference in scores will be presented. A positive value indicates an improvement, a negative value an impairment. 3 or 6 months post-surgery, 12 and 24 months post-surgery
