Description: Noise-induced hearing loss continues to be one of the most common occupational disorders, even in workplaces where workers are protected by hearing loss prevention programs. This study builds on a unique relationship between the research team and a major manufacturing company to develop a comprehensive, “mixed method” approach for assessing hearing loss prevention program effectiveness. This study is developing and conducting novel qualitative and quantitative assessments of different elements of hearing loss prevention programs at ten participating facilities, and relating these assessments to observed and expected rates of hearing loss among workers. This research will result in the development of a practical tool for assessing hearing conservation effectiveness and enhanced prevention of noise induced hearing loss.
