Older adults typically have trouble identifying the speech they hear, especially in noisy environments. Fortunately, compared to younger adults, older adults are better able to compensate for difficulties identifying the speech they hear by recruiting the visual system. However, the extent to which older adults can benefit from visual input, and how this influence relates to age-related changes in brain structure and function, have not been thoroughly investigated. The general purpose of this study is to determine how age-related changes in brain structure and function affect how well people hear and see. This study seeks participants with normal hearing to mild hearing loss, who also have normal or corrected-to-normal vision.
In the first arm of this study (Pro00063109) we developed a list of questions that will be utilized in a new quality of life questionnaire for cochlear implant users. We developed a survey to be used in the clinical setting based on these questions. We would like to gather data from a large number of implant users in order to validate the questionnaire. In the survey subjects are asked how hearing loss and having a cochlear implant affects their life. Enrolled subjects will complete the combined experimental survey paired with the current gold standard quality of life measures at two time points one month apart, greater than a year after receiving cochlear implantation.
This project, funded by the National Institutes of Health, is being conducted to learn how hearing impairment affects how people hear certain sounds and understand speech and to provide a scientific basis for diagnosis and rehabilitation of hearing loss. Volunteers who meet the eligibility requirements may enroll in this study, which will include measurements of hearing tones and noise, understanding speech, and completing questionnaires. Participants 18 years of age and older with normal hearing or hearing loss are currently being recruited. Several visits of 1.5-2 hours each over a period of 3-6 weeks are required and scheduling is flexible. Compensation for time will be provided and parking validated.
This project, funded by the National Institutes of Health, is being conducted to determine the effects of aging on hearing, understanding speech, and brain functions. This study will provide a scientific basis for diagnosis, rehabilitation and prevention of hearing loss due to aging. Volunteers who meet the eligibility requirements may enroll in this study, which will include measurements of hearing, making listening judgments of sounds, behavioral tasks, questionnaires, and MRI scanning of the brain. Participants 60 years of age and older with normal hearing or hearing loss are currently being recruited. Three visits of 2-3 hours each are required and scheduling is flexible.
