- Primary Outcome Measures
Name Time Method Comparison of fitting method A versus B in regard to sound quality 2 months The number of subjects who prefer the hearing aid setting achieved with hearing aid fitting method A versus B will be measured in the lab with the aid of sounds presented via loudspeakers. This will be measured with the Multiple Stimuli with Hidden Reference and Anchor (MUSHRA) method.
- Secondary Outcome Measures
Name Time Method Comparison of fitting method A versus B in regard to speech intelligibility in noise 2 months The speech intelligibility in noise with hearing aid fitting method A versus B will be measured with the aid of the Oldenburg sentence test in dB Speech Reception Treshold (SRT).
