Outcome Measures
Primary Outcomes (1)
Speech Reception Thresholds (SRT) Assessed Via Sentence Scores in Spatially Separated Adaptive Noise
Paired difference in dB SRT between treatment and control, with their applicable noise reduction feature enabled. The speech recognition threshold (SRT) examines at which level the participant can repeat 50% of the speech material correctly. These scores may be negative or positive numeric values. Lower dB SRT scores indicate a better outcome.
