摘　　要：无关语言噪声是开放式研究室的主要干扰源,通过引入掩蔽声可降低语言清晰度,从而降低无关语言噪声对人员工作的干扰.本文通过实验测试研究了3种掩蔽声源(伪语声、泉水声、类语言噪声)对高校开放式研究室科研人员专业文献阅读的影响,并将实验结果与2种无掩蔽声环境(即安静环境和纯语言噪声环境)进行对比.结果表明:在无关语言噪声环境下,掩蔽声的引入确实能提升高校开放式研究室的声环境质量,并且其提升效果与掩蔽声源类型和语言传输指数(Speech Transmission Index,STI)有关.本文还探讨了性别、噪声敏感度等个人因素对开放式研究室掩蔽声环境感受的影响.相关结论可为开放式研究室声学设计和研究提供参考.Irrelevant speech is a main disturbing source in open-plan research offices. The introduction of masking sound can reduce speech intelligibility and thus reduce the interference of irrelevant speech. In this paper,the effects of three masking sounds( speech-like pink noise,spring water,babble) on professional literature reading tasks in university open-plan research offices were studied. The results were then compared with those of unmasked conditions( quiet and speech environments). The results show the acoustic environment quality of university openplan research offices can be improved by the introduction of masking sound,and the effects are related to the type of masking sources and speech transmission index( STI). This paper also discussed the effects of personal factors( gender and noise sensitivity) on participants’ acoustic perceptions in open-plan research offices. The conclusions can provide references for the design and research of open-plan research offices.
