Abstract
This report describes research on the audiometric data set of Alcoa which the principal investigator has carried out with funding from a KOI SERCA between 1998 and 2001. During the grant period, a large audiometric data set was analyzed to determine whether risk factors for noise induced hearing loss could be identified among the employees. Originally, the data set from one aluminum smelter was analyzed. Later, the analysis was expanded to other Alcoa audiometric sets. Linkage was made with an industrial hygiene data set to improve noise exposure assessments. The annual rate of hearing loss in employees was calculated, and this was compared with other metrics of hearing loss, such as the proposed ANSI standard for evaluation of hearing conservation program effectiveness. Progress occurred on the development of an audiometric case definition; a board of experts was convened, and these experts performed analysis on a set of audiograms. Risk factors for noise induced hearing loss were evaluated through both a case-control and a prospective approach using a Cox-proportional hazards model.
