The noise produced in demolition sites can mask safety-critical sounds that inform operators about task conditions and hazards. These problems are exacerbated in teleoperated demolition, where the separation between operator and site compromises operators' situation awareness and cognitive loads. This paper assessed the effects of environmental sounds with and without attenuation on the operators' performance and response (e.g., stress, attention, task engagement) during teleoperated demolition. Eighty participants completed three virtual demolition tasks under different environmental sound conditions, i.e., no sound (NS), unfiltered sound (US), and filtered sound (FS) with 20-dB attenuation of background noise and robot's sounds to allow focus on safety and task conditions. The results show that US induced more stress than NS and FS. Also, FS resulted in fewer collisions, faster reaction times, and greater attention and task engagement than US. These results can support the design of sound feedback interfaces for teleoperation in construction.

选择性环境声音衰减对远程操作拆除中操作员的表现、压力、注意力和任务投入的影响


拆除现场产生的噪音会掩盖对安全至关重要的声音，这些声音会告知操作员有关任务条件和危险的信息。这些问题在远程操作拆除中更加严重，其中操作员和现场之间的分离损害了操作员的态势感知和认知负荷。本文评估了在远程操作拆除过程中，有和没有衰减的环境声音对操作员的表现和反应（例如，压力、注意力、任务参与）的影响。80 名参与者在不同的环境声音条件下完成了三项虚拟拆除任务，即无声 （NS）、未滤波声音 （US） 和滤波声 （FS），背景噪声和机器人声音衰减 20 dB，以便专注于安全和任务条件。结果表明，US 比 NS 和 FS 诱导的压力更大。此外，FS 导致的碰撞更少，反应时间更快，注意力和任务参与度比 US 更高。这些结果可以支持建筑中用于远程操作的声音反馈接口的设计。
