Eight patients had a conductive/mixed (con/mix) hearing loss.

Subjective outcome was evaluated by three questionnaires: 1) International Outcome Inventory for Hearing Aids, 2) Speech, Spatial and Qualities of Hearing Scale 12, and 3) a questionnaire on frequency and duration of use.RESULTS: No major complications occurred. The mean aided PTA4 was lowered by 23dB. SDS was increased by 40{\%} at 50dB, by 34{\%} at 65dB, and by 12{\%} at 80 dB SPL. SRT50{\%} in noise improved 5.2 dB. 58{\%} of the patients used the device daily and 83{\%} at least 5 days a week. 50{\%} used the device ≥ 8 hours and 75{\%} ≥ 4  hours a day. Mean International Outcome Inventory for Hearing Aids score was 3.7, corresponding to beneficial outcome. In Speech, Spatial and Qualities of Hearing Scale 12, {"}quality of hearing{"} scored especially high.
