Is there such a thing as the perfect alarm tone? We think so (and this is what it might sound like)

Waking up right is important

- Advertisement -

Waking up groggy never feels right. And how we wake up can not only affect our mood and the day’s outlook, but also our cognition and mental performance. In some instances, grogginess after waking has the potential to be dangerous several hours later, by reducing our performance in critical decision-making (such as in health settings, emergency responses, security or while driving).

How does the brain wake up?

Transitioning from sleep to alertness does not follow an on/off switch-like system, as brain imaging techniques have revealed. Waking relies on complex biological processes, including increased blood flow allocation to the brain. Studies show the brain regions important for alert performance (the prefrontal cortical regions) take longer to “start-up” than other areas (such as the basal ganglia) which are important for arousal. This means you can be awake, but not quite with it.

Is sound frequency and tune important?

But when it comes to choosing an alarm, what exactly is the best choice? A growing body of evidence suggests different alarm sounds can positively influence human performance after waking. Our systematic review published in 2020 showed temporal frequencies (the pitch of the sound as measured in Hertz) around 500 Hz are better at arousing young children than 2000+ Hz varieties.

What can I do to improve my waking alarm?

What does all this mean for the day-to-day? Well, given all of the above, we believe the perfect alarm must sound something like this:

• it has a melody you can easily sing or hum along to
• it has a dominant frequency around 500 Hz, or in the key of C5
• it is not too fast or too slow (100 – 120 beats per minute is ideal)

Conclusion

In conclusion, the perfect alarm tone is not just about being loud, but also about being melodic and having the right frequency. By incorporating these elements, we can create an alarm that not only wakes us up, but also helps us feel more alert and awake.

FAQs

Q: What is the best alarm tone for waking up?
A: The best alarm tone is one that has a melody you can easily sing or hum along to, a dominant frequency around 500 Hz, and is not too fast or too slow (100 – 120 beats per minute is ideal).

Q: Why is the frequency of the alarm important?
A: The frequency of the alarm is important because it can affect how well we wake up and how alert we feel. Research has shown that temporal frequencies around 500 Hz are better at arousing young children than 2000+ Hz varieties.

Q: Can I use my favorite song as an alarm?
A: Yes, using your favorite song as an alarm can be a great way to wake up more alert. Research has shown that music can be an effective way to counteract sleep inertia after a short nap, and even more so if it is music you personally enjoy.

Q: How loud should my alarm be?
A: The loudness of your alarm will depend on your age and the stage of sleep you are in. Younger people and those who are in a deeper stage of sleep may require a louder alarm to wake them up.
