Tinnitus is the number one disability among veterans and it affects at least one in every 10 American adults. Veterans have higher rates of tinnitus than the general public due to the noise levels they encounter while in the service, including gunfire, machinery, aircraft, and much more. Over 150,000 veterans were diagnosed with tinnitus in 2015 and nearly 1.5 million veterans are currently receiving disability benefits for it.
