The most common occupational health problems in this professional group are visual problems due to working with video display units, voice disorders due to continuous talking, and auditory problems due to communication headset usage and acoustic shocks.[3,4] However, relatively few studies have been published on the risk of hearing impairment in call center operators due to usage of communication headsets. Such a situation has probably been in part due to the difficulties in the measurement set-up and in the evaluation of the exposure itself.
