Summary
The present study will confirm the clinical benefit of 2 different released hearing aid models for speech understanding (in noise). Participants with mild to severe hearing impairment will be fit binaurally with Unitron hearing aids and will perform a standardized speech discrimination test in noise with and without hearing aids.
