Aiming at the noise problem of coal mine air shaft room,the effective treatment method of computer acoustic simulation and new sound-absorbing material was proposed and discussed deeply.Firstly,the noise source was analyzed in depth,then the noise in the working environment was simulated and calculated by using acoustic simulation software,and a noise control plan based on the calcula-tion results was designed.The research shows that by using the new sound-absorbing material and using the comprehensive treatment method of noise reduction,sound insulation,ventilation,and assembly,the noise of the air shaft station after treatment can meet the ClassⅡ standard in the Emission Standard for Industrial Enterprises Noise at Boundary(GB 12348-2008),achieving standard emission of boundary noise.
