Tl dr: High pitch alarm sounds are less effective at waking up children & teenagers than medium/low pitch alarm sounds. ![]() They didn't test different pitch tones, however. (2006) again compared tone vs voice awakening, and found that verbal messages were more effective at waking up children. They concluded that it is the high frequency of the smoke alarm which is resulting in lower awakening rates among children.Ī later study by Smith, et. The authors had hypothesised that verbal messages would awaken children, however it turned out that the T3 alarm was also very effective when compared to standard Australian smoke alarms. Table 2: Time taken for children to wake-up using different alarms (% of those who did wake) Table 1: Percent of children who awoke to each alarm signal International Standard for audible emergency evacuation signal The wake-up stimuli in their test included: (2004) investigated the effect of different types of alarms/sounds for waking up children (n=14-20 for the different sounds). The alarm clock is designed as a universal alarm clock that fits a silent morning and minimal functions to avoid confusion. 11 of the 20 juniors did not wake up on either of the two nights that the test was performed.Īs a follow-up, Bruck, et.

The Canadian government produced this nice document about their research, but I'm sure there is a boatload of research on the topic. The point of this research being that the sound needs to convey danger and urgency to the people who hear it, regardless of age, gender, social, and ethnic background. There is plenty of research on more important alarms, like fire alarms. ![]() I'll let you decide whether this counts as "real research."Įdit: Had a bit of a brainwave. It may not be rigorous or peer-reviewed, but at least it followed the scientific method. And this paper used alarm clocks to stimulate fetuses.īut the best article I could find comparing different types of clocks is this article on Slate. Here is one that says "alarm clocks, meals, or work schedules are strong influences on circadian rhythms in human beings". Listen to Soothing Alarm Clock Sounds by Steven Cravis on Apple Music.
