Telephone call centers improve a company’s brand image and competitiveness. Interactive computer-telephone service, as performed in telephone call center, is a special group for study because VDTs are used interactively during telephone calls. This work requires repetitive movements and a prolonged static sitting posture. Communication skills, cordiality, responsibility and efficiency are expected from operators under time pressure. These work conditions may cause visual fatigue, musculoskeletal disorders and hearing loss. In this study the Nordic Musculoskeletal Questionnaire (NMQ) and ergonomics hearing losses questionnaire are used to investigate musculoskeletal discomfort and hearing loss syndromes in call center operators. The results showed that the prevalence rate of discomfort for these groups is between 83.8% to 91.7%. In particular neck, shoulder, upper back and lower back, cause more discomfort than the other limbs. In the ergonomic hearing loss investigation, 61.8% of telephone customer service workers sustained head and ear discomfort in association with jobs, among which 58.9% of the discomfort was ear discomfort. The results are good for computer-telephone operations to improve their VDT workstation and enhance their health.
