Given the ease with which the diverse array of environmental sounds can be understood, the difficulties encountered in using auditory alarm signals on medical devices are surprising. In two experiments, with nonclinical participants, alarm sets which relied on similarities to environmental sounds (concrete alarms, such as a heartbeat sound to indicate "check cardiovascular function") were compared to alarms using abstract tones to represent functions on medical devices. The extent to which alarms were acoustically diverse was also examined: alarm sets were either acoustically different or acoustically similar within each set. In Experiment 1, concrete alarm sets, which were also acoustically different, were learned more quickly than abstract alarms which were acoustically similar. Importantly, the abstract similar alarms were devised using guidelines from the current global medical device standard (International Electrotechnical Commission 60601-1-8, 2012). Experiment 2 replicated these findings. In addition, eye tracking data showed that participants were most likely to fixate first on the correct medical devices in an operating theater scene when presented with concrete acoustically different alarms using real world sounds. A new set of alarms which are related to environmental sounds and differ acoustically have therefore been proposed as a replacement for the current medical device standard.

在声音中搜索含义:在视觉环境中学习和解释警报信号。

鉴于可以轻松理解各种环境声音,在医疗设备上使用听觉警报信号遇到的困难令人惊讶。在两个有非临床参与者的实验中,将与环境声音(具体警报,例如表示“检查心血管功能”的心跳声音)相似的警报集与使用抽象音调代表医疗设备功能的警报进行了比较。还检查了警报在听觉上的差异程度:每个警报集在听觉上不同或相似。在实验1中,在声音上也不同的具体警报集比在声音上相似的抽象警报更快地获知。重要的,根据当前全球医疗设备标准(国际电工技术委员会60601-1-8,2012)的指南设计了类似的抽象警报。实验2重复了这些发现。此外,眼动追踪数据显示,当参与者使用现实世界的声音发出具体的声学不同警报时,参与者最有可能首先将目光聚焦在手术室场景中的正确医疗设备上。因此,已经提出了一组与环境声音有关并且在声学上不同的警报,以代替当前的医疗设备标准。(PsycINFO数据库记录(c)2020 APA,保留所有权利)。眼动数据显示,当参与者使用现实世界的声音发出具体的声学差异警报时,参与者最有可能首先将目光聚焦在手术室场景中的正确医疗设备上。因此,已经提出了一组与环境声音有关并且在声学上不同的警报,以代替当前的医疗设备标准。(PsycINFO数据库记录(c)2020 APA,保留所有权利)。眼动数据显示,当参与者使用现实世界的声音发出具体的声学差异警报时,参与者最有可能首先将目光聚焦在手术室场景中的正确医疗设备上。因此,已经提出了一组与环境声音有关并且在声学上不同的警报,以代替当前的医疗设备标准。(PsycINFO数据库记录(c)2020 APA,保留所有权利)。
