If you are aware of the risks of noise pollution and have enough forethought, you can make the decision to invest in specifically manufactured, quieter equipment. This may be that you select a machine which uses quieter cooling fans or whose engineering tolerances are higher, or you could select equipment for processes which are themselves quieter. These machines may come with a higher upfront
