| Study explains 'cocktail party effect' in hearing impairment Posted: 21 Apr 2021 01:00 PM PDT Plenty of people struggle to make sense of a multitude of converging voices in a crowded room. Commonly known as the 'cocktail party effect,' people with hearing loss find it's especially difficult to understand speech in a noisy environment. New research suggests that, for some listeners, this may have less to do with actually discerning sounds. Instead, it may be a processing problem in which two ears blend different sounds together - a condition known as binaural pitch fusion. |
