Abstract

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遥控爆破中操作员的表现、压力、注意力和任务参与度的影响

爆破现场产生的噪音会掩盖对安全至关重要的声音，而这些声音能让操作员了解任务条件和危险。这些问题在远程操作的拆除作业中更为严重，因为操作员与现场之间的分离会影响操作员的情况意识和认知负荷。本文评估了环境声音衰减和不衰减对操作员在远程操作拆除过程中的表现和反应（如压力、注意力、任务参与度）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爆破任务，即无声音（NS）、未过滤声音（US）和过滤声音（FS），其中过滤声音对背景噪声和机器人的声音衰减了 20 分贝，以保证操作者能够专注于安全和任务条件。结果表明，US 比 NS 和 FS 引发的压力更大。此外，与 US 相比，FS 能减少碰撞、加快反应时间、提高注意力和任务参与度。这些结果有助于为建筑工程中的远程操作设计声音反馈界面。

期刊介绍： Automation in Construction is an international journal that focuses on publishing original research papers related to the use of Information Technologies in various aspects of the construction industry. The journal covers topics such as design, engineering, construction technologies, and the maintenance and management of constructed facilities. The scope of Automation in Construction is extensive and covers all stages of the construction life cycle. This includes initial planning and design, construction of the facility, operation and maintenance, as well as the eventual dismantling and recycling of buildings and engineering structures.
