Auditory roughness in medical alarm sounds is an important design attribute, and has been shown to impact user performance and perception. While roughness can assist in decreased signal-to-noise ratios (perceived loudness) and communicate urgency, it might also impact patient recovery. Therefore, considerations of neuroscience correlates, music theory, and patient impact are critical aspects to investigate in order to optimise alarm design.
听觉粗糙度是医疗报警声音的一个重要设计属性，已被证明会影响用户的性能和感知。虽然粗糙度可以帮助降低信噪比（感知响度）并传达紧急程度，但它也可能会影响患者的康复。因此，考虑神经科学相关性、音乐理论和患者影响是优化报警设计时需要调查的关键方面。
