办公空间的声环境是影响员工工作绩效的重要因素。现有的研究主要集中在声环境对单一视觉认知工作表现的影响上，而本研究考虑了多任务视觉认知工作。选取41名被试参加不同声环境下的多任务视觉认知行为认知实验。研究了不同典型声源类型、声压级和混响时间对设计办公室多任务视觉认知表现的影响。结果显示如下。首先，声源类型对被试工作绩效的反应时间有显著影响。与周围环境（平均2.838 s）相比，音乐声音下的反应时间最短（平均2.560 s）。其次，交通噪音和空调噪音的增加会显著降低位置的记忆精度。例如，当交通噪声从50 dBA增加到65 dBA时，位置的记忆精度降低了4.42%。第三，语音混响的增加会有效缩短反应时间，提高图形的记忆精度。随着语音混响时间从0.3 s增加到1.5 s，反应时间减少0.274 s。同时，图形存储精度提高了2.03%。此外，参与者的个人特征也会影响视觉认知工作。因此，室内声学设计有望提高员工的视觉认知工作绩效。
The acoustic environment in the office space is a significant factor affecting workers' performance. Whereas existing research focuses mainly on the impact of the acoustic environment on single visual cognitive work performance, this study considers multitask visual cognitive work. Forty-one respondents were selected to participate in the multitask visual cognitive-behavioural cognitive experiment under different acoustic environments. The effects of different typical sound source types, sound pressure levels, and reverberation times on the performance of multitask visual cognition in design offices were examined. The results revealed the following. First, the sound source types have a significant impact on the reaction time of participants' work performance. Compared to the ambient environment (mean = 2.838 s), the reaction time performance is shortest under music sound (mean = 2.560 s). Second, the increase in traffic noise and air-conditioning noise will significantly reduce the memory accuracy of the location. For instance, when the traffic noise increases from 50 dBA to 65 dBA, the memory accuracy of the location is reduced by 4.42%. Third, the increase in the reverberation of speech will effectively shorten the reaction time and increase the memory accuracy of graphics. As the reverberation time of speech increases from 0.3 s to 1.5 s, the reaction time is reduced by 0.274 s. Meanwhile, 2.03% of the memory accuracy of graphics increased. Furthermore, the personal characteristics of the participants also affected visual cognitive work. Therefore, it is expected to improve the visual cognitive work performance of employees for room acoustic design.
