| Abstract |
Computers with CRT monitors are increasingly used for control of production facilities. An inventory of the frequency of such workplaces in Germany in 1991 and 1994 revealed that they are most common in the machinery, electrical, chemical and automobile industries. In 1994, there was a total of 383,869 workplaces with CRT monitors. Measurement of the noise exposure in 80 such workplaces yielded an average sound pressure level of 77dB(A). In 15% of the workplaces the noise exposure was found to be below the permissible levels, ranging from 55 to 85dB(A). In the remaining workplaces the permissible levels were exceeded by an average of 10dB(A). In half of the workplaces the machines were equipped with full or partial acoustic enclosures, or separations were installed to shield off the noise sources. |
