Hearing damage is the No. 1 disability in the war on terror, according to the Department of Veterans Affairs, and some experts say the true toll could take decades to become clear. Nearly 70,000 of the more than 1.3 million troops who have served in the two war zones are collecting disability for tinnitus, a potentially debilitating ringing in the ears, and more than 58,000 are on disability for hearing loss, the VA said.
"The numbers are staggering," said Theresa Schulz, a former audiologist with the Air Force, past president of the National Hearing Conservation Association and author of a 2004 report titled "Troops Return With Alarming Rates of Hearing Loss."
U.S. Army Sgt. Ryan Kahlor listens for sounds as his hearing is tested at Balboa Navy Medical Center in San Diego, Feb. 6, 2008. Kahlor's hearing was damaged by exposure to multiple IAD blasts in Iraq.
