Perceptual comparison of noise reduction in hearing aids
Resumé
Knowledge on perceptual consequences of single-microphone noise reduction in hearing aids is limited. We developed and evaluated a filtering method that allowed us to directly compare noise reduction systems from different hearing aids. Using this method, we compared noise reduction from four different hearing aids in a paired-comparisons design. Preference strength of our normal hearing subjects appeared to differ between noise reduction systems as well as between SNRs. Both factors are relevant for the interpretation of previous noise-reduction studies as well as for hearing- aid selection and fine-tuning.
