title: Survey of noise exposure and background noise in call centers using headphones.
abstract: Call centers represent one of the fastest growing industries. However, there are health and safety hazards unique to this new industry. One of these potential hazards is hearing impairment caused by headsets. In this study, noise exposure assessment was performed at 21 call centers and for 117 operators. Although call center background noise does not contribute to noise exposure, it impacts working conditions and influences the headset volume setting. It was therefore measured at the same time as exposure to noise. Results revealed that although the risk of hearing impairment was generally low, exposure could exceed the European Union regulation upper and lower exposure action values. Besides exposure to noise, background noise levels are often high with regard to recommendations for office workers. Results are discussed and some recommendations are given, issued from on-site observations. Their application is intended to ensure the absence of excessive exposure to noise and improve acoustic comfort.
