Summary

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.

Conditions

• Hearing Loss
• Normal Hearing

Interventions

Type	Name	Description
DEVICE	Hearing Aid without NR and BF	Each participant will be fitted with the Noise Reduction (NR) and Beamforming (BF) disabled. Disabled means that no sound processing algorithm that removes noise from the speech signal is active.
DEVICE	Hearing Aid with NR	Each participant will be fitted with the Noise Reduction (NR)(Sound Changing) program on the same hearing aid. Noise Reduction principle is a sound processing algorithm to remove noise from a speech signal to improve the speech intelligibility and comfort. The Noise Reduction is working spatially independent.
DEVICE	Hearing Aid with BF	Each participant will be fitted with a beam forming program on the same hearing aid. Beam forming (BF) principle is a sound processing algorithm to remove noise from certain directions to improve the speech intelligibility and comfort.
