Auditory Training to Improve Hearing After Mild Traumatic Brain Injury for Adults Aged 18 to 55

What this Trial Is About

Researchers are studying whether special sound training exercises can help adults aged 18 to 55 who have had mild traumatic brain injuries mTBI improve their hearing. These injuries may cause difficulties in hearing clearly, especially in noisy environments or in locating sounds. The study aims to see if training methods that helped healthy people can also benefit those with mTBI and hearing problems, which may improve treatment options for affected individuals, including soldiers and veterans. The study includes two types of training Speech in Noise SPiN training and Spatial Hearing training. Participants will be randomly assigned to groups receiving either the training or control activities. For SPiN training, participants use a tablet and earphones at home for up to two 10-minute sessions daily over eight days. The Spatial Hearing training uses a 360-degree speaker setup where participants identify sound locations, with feedback provided to the training group. Control group participants may be offered training after the study. During the study, participants undergo tests to measure changes in hearing ability, sound localization, and brain responses to sounds from baseline through about one month after training. Assessments include hearing in noise scores, sound localization accuracy, and brain activity measures. The study monitors progress closely and aims to understand how these training methods affect hearing challenges after mild brain injury.
