PC-based Rehabilitation of Auditory Function

Detailed Summary

Many older subjects experience difficulty in understanding speech in noisy environments. Part of this problem is related to changes that occur in the ear with age and compromise the hearing of high-pitched sounds. Another part of the problem with speech understanding relates to changes with age in the neural circuits of the brain that process different speech sounds. Evidence suggests that these changes in neural circuits are particularly large if hearing loss is present. Thus, while hearing aids may help compensate for hearing deficits by amplifying speech sounds, additional treatment is necessary to restore optimal neural connections in the brain so that speech sounds can be accurately distinguished from each other. We are developing PC-based training programs in an attempt to restore optimal neural connections. The current randomized trial will evaluate whether two months of training to improve the ability to discriminate different consonant sounds in noise will also improve the understanding of continuous speech and enhance auditory memory and other high-level auditory functions.
