The Analysis And Control Of Fan Room's Noise

This paper is based on the theory of environmental science,systematology and noise control engineering.Noise control system and comprehensive harness of fan room have been researched. By the investigate,and measure of fan room noise. Sound production principle,acoustics characteristic and the law of attenuation propagation have been analyzed.Thus,the sound field model of fan roo has been put for put forward ward.It is proved by measuring noise of fan room of JCFK,that there are pretty good agreements between estimation and experiments.Then,this model is applied for the practical engineering of noise control in fan room.The ways to connection qualitative with quantitative,analysis in theory with policy decision in practice are successfully used and the optimal scheme of noise control is achieved.Moreover,the effect of the optimal scheme is estimated.This paper makes considerable headway about not only the research range and content but also the theoretical basis and research method.It has the important practical value.
