  Mining, and Oil and Gas Extraction (MOG) Statistics
          At a glance
            * View hearing loss trends and statistics among Mining, and Oil and Gas Extraction (MOG) workers.
            * Approximately 23% of all MOG workers have hearing difficulty.
            * About 11% of all MOG workers have tinnitus.
            * 28% of noise-exposed MOG workers report not wearing hearing protection.
        Noise exposure and hearing protection
          * About 61% of all workers in MOG have been exposed to hazardous noise.1
          * 28% of noise-exposed MOG workers report not wearing hearing protection.2
        Hearing loss and tinnitus
          * Approximately 23% of all MOG workers have hearing difficulty.1
          * About 11% of all MOG workers have tinnitus.3
          * About 24% of noise-exposed tested Mining workers and 14% of noise-exposed tested Oil and Gas Extraction workers have a material hearing impairment.4 Hearing impairment is hearing loss that impacts day-to-day activities.
          * 17% of noise-exposed tested MOG workers have hearing impairment in both ears.5
        Trends
        Trends in hearing loss among noise-exposed tested mog workers (1981-2010)6
          * The prevalence for MOG increased 1% over 20 years (1991-2010) as compared with a 1% increase for all industries during the same time period.
          * The incidence for MOG increased less than 1% over 10 years (2001-2010) as compared with a 1% reduction for all industries during the same time period.
          * The adjusted risk for MOG decreased 7% over 10 years (2001-2010) as compared with a 12% reduction for all industries over the same time period. There was insufficient sample size to examine the MOG adjusted risks from 1986-2000, and this was not plotted.
