Cement plant noise has the characteristics of fixed sound source points, complex sound source types, and high sound pressure levels. For example: crushers, raw material mills, coal mills, cement mills, fans, air compressors, blowers, etc. have sound pressure levels of 80-120 dB (A), which are strong noise sources.According to the…

The acoustic-solid coupling method is then used to numerically predict the coupled noise of the forage crusher's air noise and mechanical noise. The primary source of noise in forage crushers is aerodynamic noise. Mechanical noise from unbalanced rotor excitation, as well as material and mechanical structure collisions, play important roles in ...

The findings for noise and silica exposure are summarized in Table 1 by job type. For measurements using the PEL criterion, only groundsmen exceeded the PEL of 90 dBA, although crusher mechanics approached this limit with a mean of 89.1 dBA. When exposures exceed the PEL, exposures must be reduced below 90 dBA, and until
