Area of Grinding section PA has maximum noise level by overall is 106.2 dBA while minimum noise level is 93.6 dBA. Earplug and earmuff used concurrently represent most precise choice because owning NRR equal to 2085 dB. Second alternative that is by using foam earplug with NRR equal to 1725 dB. Third alternative by using active noise reduction headsets with NRR equal to 1507 dB. From quisioner which have been filled all worker assume the noise in place is high enough and situation in this unit longer also excelsior.
