摘　　要：热、声环境是室内环境重要组成部分,本研究旨在探讨噪音声压级、频率和温度对人体舒适性的综合影响。研究选取18名受试者参与实验,设置3种温度条件(22℃,25℃,28℃),4种噪声声压级(50 dB(A),55 dB(A),65 dB(A),75 dB(A))和3种频率范围(低频段:20~160 Hz,中频段:160~2500 Hz,高频段:2500~20000 Hz)。结果显示,频率范围对人体舒适性无显著影响;而温度与噪声声压级的交互作用显著影响人体热舒适,22℃环境下的热不适显著大于25℃、28℃环境下的热不适且22℃环境下热不适随噪声声压级增加而增加。研究结果可为舒适室内环境的创造提供参考。Thermal environment and acoustic environment are important part of indoor environment.The aim of this study is to investigate the comprehensive influence of noise sound pressure level,frequency and temperature on human comfort.The study selected 18 subjects to participate in the experiment,which contain three temperature conditions(22℃,25℃,28℃),four noise sound pressure levels(50 dB(A),55 dB(A),65 dB(A),75 dB(A))and three frequency ranges(low frequency:20~160 Hz,middle frequency:160~2500 Hz,high frequency:2500~20000 Hz).The results show that the frequency range has no significant effect on human thermal comfort and the interaction between temperature and noise sound pressure level significantly affects human thermal comfort.The thermal discomfort at 22℃is significantly greater than that at 25℃and 28℃and the thermal discomfort increases with the increase of noise sound pressure level at 22℃.This study can provide reference for creating a comfortable indoor environment.
