Condition: Auditory Diseases, Central · Sponsor: VA Office of Research and Development
Since 2000, at least 250,000 U.S. Service members have experienced a blast-related mild traumatic brain injury. A retrospective analysis of over 100,000 post-9/11 Veterans shows that blast injury more than doubles the risk of a diagnosed auditory problem. Many blast-exposed Veterans experience "functional hearing difficulties" (FHDs): problems in challenging listening environments despite clinically normal hearing as measured by the pure-tone audiogram. VA audiologists have begun using low-gain hearing aids to treat FHDs, but there are no concrete guidelines for this application given standard procedures rely on the pure-tone audiogram. This study proposes a data-driven approach called speech-based audiometry (SBA), which optimizes hearing aid gains from a patient's responses to speech stimuli in aided conditions. This trial will assess the behavioral (speech recognition in noise, subjective listening difficulty) and neurophysiological (functional neuroimaging during a speech recognition task) benefits of low-gain hearing aids programmed conventionally or with SBA among blast-exposed Veterans with FHDs.
