摘要
现有的室内声源预测模型采用室内声源等效为室外声源声功率级法,该方法在较为复杂的室内环境中以及在声源声功率级参量未知的情况下具有一定的局限性。相比较室外噪声模型预测系统的研究,国内目前关于室内噪声预测模型系统的研究较为薄弱。对此,基于HJ 2.4-2009等技术导则,以某风机房为例,对室内噪声预测模型进行优化,并设计室内噪声预测模型系统的模块化程序,采用Eclipse运行设计程序,简化室内模型预测运算,同时为室内噪声预测模型系统的研究提供一些建议。
The existing indoor sound source prediction model adopts the indoor sound source equivalent to the outdoor sound source sound power level method.This method has certain limitations in the more complex indoor environment and when the sound source sound power level parameters are unknown.Compared with the research of outdoor noise model prediction system,the research on indoor noise prediction model system in China is relatively weak.Based on HJ 2.4-2009 and other technical guidelines,this paper takes a laboratory fan as an example,optimizes the indoor noise prediction model,designs the modular program of the indoor noise prediction model system,and uses eclipse to run the design program to simplify the indoor model prediction operation and provide suggestions for the research of indoor noise prediction model system.
