Assessed via Abbreviated Profile of Hearing Aid Benefit (APHAB) questionnaire. 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.

Assessed via the Speech, Spatial and Qualities of Hearing Scale (SSQ) questionnaire. Measuring change of speech, spatial and hearing experiences with the Active Osseointegrated Steady-State Implant System. The Total score summarizes the parameters speech, spatial and hearing. A scale from 0 to 10 is used, where 0 represents "can not hear at all", and 10 "hear perfectly". An increase of an SSQ value reflects an improvement. The change in scores will be presented. A positive value indicates improved hearing, a negative value indicates impaired hearing.
