Abstract
Prevalence of Hearing Loss and Tinnitus with Correlation to the Usage of Protective Hearing Equipment among Airport Workers
Highlights
Sound and noise are part of the same auditory continuum
Frequent audiometric screening tests as well as enforcement of protective hearing equipment (PHE) usage by airport field workers needs to be introduced by the airport administrations
Because fewstudies have assessed the prevalence of tinnitus among aircraft workers in the Middle East, we assumed that 50% currently suffer from tinnitus to achieve the maximum sample size
Summary
Sound and noise are part of the same auditory continuum. Noise has been defined by the National Institute for Occupational Safety and Health as «any unwarranted disturbance within a useful frequency band» [1]. 10 million individuals in the U.S suffer from occupational hearing loss [6] In Saudi Arabia (KSA), Ahmed et al has shown that the prevalence of hearing impairment in industrial workers exposed to noise is 39.3% in comparison to only 4.5% of non-noise exposed worker [7]. These levels are comparable to China where 42% of airport maintenance workers are estimated to suffer from occupational hearing loss [8]
