Tinnitus is among the most prevalent medical complaints soldiers have when returning from Operation Iraqi Freedom/ Operation Enduring Freedom (OIF/OEF). Soldiers with clinically significant levels of tinnitus often suffer from anxiety, depression, sleep disruption, and difficulty concentrating. Currently, there is no standard tinnitus treatment protocol in the military system and limited clinical efficacy on the NTTP and COTS tinnitus treatment supported by a controlled study. The proposed research will attempt to definitively establish the value of the NTTP in a military setting.
