When more than one audible alarm is heard simultaneously, discrimination may be compromised. This experiment compares near-simultaneous clinical alarms in two styles, the first are the tonal 'melodies' from the 2012/2006 version of a global medical device safety standard (IEC 60601-1-8) and the second are the auditory-icon-style recommended in the 2020 version of the same standard. Sixty-six participants were required to identify the meaning and priority of four different clinical alarms for one of the two styles of alarm (between-subjects). Alarms sounded both singly and in pairs (within-subjects). Results showed that the auditory icon alarms outperformed the tonal alarms on all measures except one, both for overall accuracy (recognizing both priority and function) and for partial accuracy (recognizing priority or function but not both). The results add to the growing body of evidence supporting the use of auditory icon alarms in clinical environments.
当同时听到多个可听警报时，可能会影响识别。本实验比较了两种风格的近乎同时发生的临床警报，第一种是来自 2012/2006 版全球医疗器械安全标准（IEC 60601-1-8）的音调“旋律”，第二种是同一标准 2020 版推荐的听觉图标风格。要求 66 名参与者识别两种警报风格（组间）中四种不同临床警报的含义和优先级。警报单独和成对（组内）响起。结果表明，在所有指标上，听觉图标警报的表现均优于音调警报，除了一个指标外，无论是在整体准确性（识别优先级和功能）还是部分准确性（识别优先级或功能，但不是两者）上。这些结果增加了越来越多的证据，支持在临床环境中使用听觉图标警报。
