Outcome Measures

Primary Outcomes (1)

  • Non-inferior speech perception with preferred Bass and Treble settings compared to the baseline Bass and Treble settings

    Co-primary endpoint #1: This endpoint is to test that speech perception scores in noise with preferred Bass and Treble settings are non-inferior to the baseline settings. Subjects will be tested at visit one with their own settings (Baseline), and then again after four weeks use of the Bass and Treble feature. The speech signal will arrive from zero degrees azimuth at a level of 65 dB SPL, the noise will also arrive from zero degrees azimuth, however the noise will adapt according to subject responses. o-primary endpoint #2: This endpoint is to test that speech perception scores in quiet with preferred Bass and Treble settings are non-inferior to the baseline settings. Subjects will be tested at visit one with their own settings (Baseline), and then again after four weeks use of the Bass and Treble feature. The speech signal will arrive from zero degrees azimuth at a level of 50 dB SPL.

    8 weeks

Secondary Outcomes (1)

  • Non-inferior sentence recognition in four-talker babble noise with Bass and Treble values set to the minimum (-6 Bass, - 6 Treble) compared to the baseline condition when the speech and noise are from the front

    8 weeks

Other Outcomes (3)

  • Subjective daily diary data on the success of the daily Bass and Treble changes made during take-home use

    8 weeks

  • Questionnaire data on the overall subjective ratings of the Bass and Treble controls (importance, confidence, ease and satisfaction)

    8 weeks

  • Incidence of adverse events as well as the severity, relationship to treatment, outcome and actions taken will be listed for each subject and summarised.
