The demand for semiconductors is increasing day by day, but the noise hazard becomes more and more serious with the increase of semiconductor production. The noise was detected using sound level meter in semiconductor production workshop. The results shows that the noise intensity of a semiconductor workshop is about 93.1 dB (A)–94.7 dB (A), which exceeds the noise limit of 9.7 dB and mainly distributes in the frequency range of 1 k–8 k, so it is belongs to high frequency noise. A sound screen was set up at 0.7 m distance from the equipment for noise protection in this paper. On the basis of comparative analysis, the transparent PC board is selected as the sound insulation material. Through theoretical calculation, it is found that the height of sound insulation screen should be at least 1.6 m in order to achieve 20.5 dB sound insulation effect and meet the requirement of noise limit.
