Retrospective Cohort Study Of Pure Tone Audiometry Threshold Shifts From Ototoxic Substance, Continuous Noise, And Impulse Noise Exposures At Tinker Air Force Base From 2005 To 2019, Marc J. Blair
Theses and Dissertations
This retrospective cohort epidemiology study sought to establish the comparative risks and potential indicators of hearing loss associated with combinations of ototoxic substances, impulse noise, and continuous noise exposure. Currently, there is not an existing model or methodology in the Department of Defense (DoD) that joins occupational exposure data and pure tone audiometric data. After developing an integrated database model for Tinker Air Force Base, the largest of three depot installations within Air Force Material Command, 2,372 individuals were grouped into eight combinations of exposure groups with a minimum three years exposure duration to hazards. The incidence rates and relative …
