开放式研究室键盘敲击声对中文文献阅读的影响研究

Influence of Keyboard Tapping Sound on Chinese Literature Reading in Open-plan Research Offices

键盘敲击声是开放式研究室内典型的声源之一。本文通过实验测试来研究不同声压级的键盘敲击声对开放式研究室人员专业文献阅读的影响。键盘敲击声以45、50、55 dB(A) 3个不同的声压级水平进行呈现,对参与者在3种声环境下阅读文献客观绩效和主观感受进行分析。结果表明,参与者的客观绩效和主观感受都受到键盘敲击声的影响并与其声压级大小相关,且在键盘敲击声为50 dB(A)的测试环境中,参与者的主观感受和客观表现都达到最佳。此外还探讨个人因素(键盘使用类型、性别和噪声敏感度)对键盘敲击声环境下文献阅读任务的影响。

Keyboard tapping is one of the typical sound sources in open-plan research offices.In this paper,the effects of keyboard tapping sounds at different sound pressure levels on personal literature reading were studied through experimental tests.Keyboard tapping sound was presented at three different sound pressure levels of 45,50 and 55 dB(A).The objective performance and subjective perception of participants who were reading literature were analyzed in these three sound environments.The results revealed that both the objective performance and subjective perception of the participants were influenced by keyboard tapping sound which was correlated with their sound pressure level,and the participants'subjective perception and objective performance reached the best in the test environment of 50 dB(A)keyboard tapping.In addition,the effects of personal factors,such as keyboard usage type,gender,and noise sensitivity,on literature reading tasks in the environment of keyboard tapping sound were also discussed.
