About
An EEG study using continuous speech stimuli to assess neural language processing in a hearing impaired population. Participants listen to short radio excerpts in different Signal to Noise Ratios (SNR) and answer comprehension questions as well as listening effort questions. We assess the effect of different algorithms on neural language processing as well as subjective listening effort. Each participant hears 12 randomized segments of speech (about 4min long each) with different settings on their hearing aid (reference condition, noise reduction algorithm, beam forming algorithm). This will be a controlled, single blinded and randomized active comparator clinical evaluation which will be conducted mono centric at Sonova AG Headquarter based in Stäfa.
