Hearing loss, including tinnitus, which is a ringing, buzzing or other type of noise that originates in the head, is the most prevalent service-connected disability among Veterans, with more than 30 million Veterans suffering from a form of it due to frequent exposure to loud noises from weaponry and aircraft. Because of the pervasiveness of hearing loss among Veterans, the Department of Veterans Affairs is recognizing October as Audiology Awareness Month by highlighting important VA research on the subject and advances made in treating Veterans with hearing loss.
