Waking up to a fire - optimising the smoke alarm signal

在任何一个晚上，在火灾紧急情况下，相当一部分人都面临着通过当前的烟雾报警器睡觉的风险。未醒的重要风险因素包括孩提时代、睡眠不足、沉睡过多、使用安眠药、酒精中毒以及60岁以上。然而，研究表明，不同的警报信号会在较低的音量下更有效地唤醒这些群体。这一创新项目将确定最佳信号，对社区公共安全、消防安全工程师、烟雾报警器行业以及我们对睡眠中认知处理的理论理解具有重要意义。

On any one night a significant proportion of the population is at risk of sleeping through the current smoke alarm in a fire emergency. Significant risk factors for not awakening include being a child, sleep deprivation, being a heavy sleeper, use of sleeping tablets, alcohol intoxication, and being aged over 60. Yet research suggests that a different alarm signal will awaken these groups more effectively at a lower volume. This innovative project will determine the best signal, with important implications for community public safety, fire safety engineers, the smoke alarm industry and our theoretical understanding of cognitive processing during sleep.
