Abstract: A videotape of a speaker saying a set of test words and phrases was presented in background noise to 10 sighted older adults and 10 older adults with severe low vision (age-related maculopathy), all of whom had normal hearing. It was found that the word- and phrase-identification scores of the low vision group were significantly lower than those of the sighted group at all levels of background noise. Strategies are suggested for optimizing face-to-face communication in background noise for people with visual impairments.
