Call center workers are dressed neatly, sit upright, wear headphones and speak softly. They work every day with call center headphones to communicate with customers. However, for these people, besides the high intensity of hard work and stress, there is actually another hidden occupational risk. Because their ear exposure to noise for a long time may cause health harm. After a long-term invisible injury, may lead to hearing loss and even cause temporary deafness.
What are the global standards for noise control of a professional headset for call center? Now let's find out!
In fact, in view of the specialization of the call center profession, there are relatively standardized requirements and controls for the noise standards and management of call center headphones worldwide.
In the United States Occupational Safety and Health Administration noise standards, the maximum for impulse noise is 140 decibels, continuous noise does not exceed 115 decibels. Under an average noise environment of 90 decibels, the maximum working limit is 8 hours. Under an average noise environment of 85 to 90 decibels for 8 hours, employees must undergo an annual hearing test.
In the European Union, occupational noise health protection appears to be more stringent. According to EU Directive 2003/10/EC, the peak sound pressure of impulse noise is 140 dB. When the peak value of noise control regulation management reaches 137 dB, a hearing protection device must be worn. When the peak value reaches 135 dB, a hearing protection device must be provided. The average noise should be limited to 87 decibels during the eight hours of each working day. Hearing protection must be worn when the average noise is between 85 and 87 decibels, and hearing protection must be provided when the average noise is between 80 and 85 decibels.
In China, the hygienic standard GBZ 1-2002 for the design of industrial enterprises stipulates that the hygienic limit of the sound level of impulse noise is 140 dB in the workplace, and the peak number of exposure pulses is 100 on working days. At 130 dB, the peak number of contact pulses on working days is 1000. At 120 dB, the peak number of contact pulses is 1000 per working day. The continuous noise does not exceed 115 decibels in the workplace. The operators of professional headsets for call center in the workplace are exposed to noise for 8 hours a day, and the average noise level limit is 85 decibels.
