Description: This study consists of two primary research elements assessed in a cohort of 45 Swedish workers. The first is a quantitative and qualitative evaluation of occupational and nonoccupational noise exposures in the cohort over a full (24 hours a day/7 days a week) one-week period. The second is to establish subjects’ baseline hearing ability and knowledge and perceptions of hearing loss prevention. This study involves several innovative research approaches, including: combination of subjective and quantitative exposure estimates; assessment of occupational and non-occupational exposures to allow for estimation of total noise exposure; and assessment of knowledge and perceptions of noise and hearing loss in among Swedes with varying levels of occupational and nonoccupational noise exposure public. The results of this study will provide a useful assessment of the sources of NIHL risk among Swedish workers in different occupations, which may be used to reduce NIHL risk in Sweden.
