Billy Martin, PhD, works with those who suffer from tinnitus and with colleagues trying to figure out how to shut off this frequently debilitating sound. The project is based in Oregon Health & Science University's Prevention Research Center. Dangerous Decibels has partnered with the Northwest Portland Area Indian Health Board, to address hearing health issues in tribes across the region. "Hearing is an essential part of tribal life. Traditions are passed on from generation to generation by word of mouth. If you lose your hearing, you're out of the loop," said Dr. Martin. The tribal communities report high levels of occupational and recreational noise exposures and Dangerous Decibels has begun working with their children.
