A Study on the Noise Reduction Methods of a Construction Secondary Products Manufacturing Company
초록
영어
This study has a purpose of identifying the degree of damage and establishing the preventing measures on the mechanical noise of 120dB over generated in the Molding machine(High pressure and vibrating)used in the Construction Secondary Products Manufacturing Company. As a results, after setting up the noise control facility made of noise control cotton cloth in the ceiling area, the average noise in and outside of the factory was reduced about 4～10dB, and that in the nearby private houses satisfies the norm (50dB). In addition, according to the result of measuring the porous block’s for sounding absorption, in the mid-high frequency band (500～4,000Hz), the sounding absorption ratio was considerably high, as approximately 55～77%.
