The purpose of this study is to determine the overlap of symptoms between posttraumatic stress disorder (PTSD) and tinnitus-related distress (ringing or buzzing in one or both ears). We will evaluate the overlap of symptoms by conducting assessments for psychological problems and tinnitus, audiometric assessments, as well as evaluate brain activity while undergoing a functional magnetic resonance imaging session (MRI). The researchers hope to learn shared and unique brain regions between tinnitus and PTSD to develop new and innovative treatment approaches
