High noise level in the production of particle is one of the main occupational hazards at the Joint-Stock Company “Ivatsevichidrev”. Studies have shown that the maximum excess of permissible levels observed at mid and high frequencies, the most harmful to humans. In the workplace, levels from 1 to 14 dB were meas- ured at workplace of shaving machine operator and the operator of the sorting chips machine PESSA, from 3 to 17 dB at machinist cutting board, from 1 to 4 dB at separator operators workplace.
