Short segments of two TV programs without audio description (AD) were presented to 25 subjects with low vision and 24 subjects with normal vision, and 29 additional subjects heard only the standard audio portions. The subjects then answered questions based on the visual information contained in the AD of the programs. The subjects with normal vision performed the best, followed by those with low vision and those who heard only the audio portion; all performed at better than chance levels. The results indicate that although AD may provide information on visual details to visually impaired audiences, some of the information in the AD may be obtained from the standard audio portion.
