Prescribed according to the occupational safety and health low noise measurement method was changed to personal sampling in the method to measure an area noise. Such method had the limit which did not evaluated characteristic of sound of occurrence and the place of origin. This study was performed to establish an engineering remedy of the work-place noise. The subject was a vibration control process of the place of business in Pusan. A simulation program applied for an engineering improvement of the work-place noise. The results were as follows: 1. An noise occurrence level of the work-place before improvement was 88~97dB(A), We applied an improvement method to be established and were expected to 80~119dB(A). 2. The level of the noise-distribution to appear in the place of origin of the work-place before improvement was 90~93dB(A) but, We executed the simulation after applied an engineering remedy and predicted 80~85dB(A). A result of the simulation blue part was changed mostly into the dark blue color. The results suggest that simulation program establishes an engineering remedy and is useful to the case to apply.
