This is what a perfect alarm sound can look like

With the return of office work – and the inability to get out of bed immediately into a moving meeting – many of us will wake up early to win the morning race.

So it’s important to make sure we are on top of our game.

But what kind of noise gives you the highest level of alertness when you wake up? Pythagoras posed a similar question about 500 BCE

He believes that specific music – songs that stimulate energy – has the ability to prevent sleep deprivation.

It also seems to have a point. Reviews has now been shown to be some of the alarm sounds that can cause our alertness.

In particular, Alarms that have the characteristic of “moving” (think ABC by The Jackson 5) has a voice that makes the listener energized and good for a good awakening.

But to understand why, we must first understand how our brain reacts to complex stimuli when we go out of sleep.

The importance of waking up

Raising groggy is not good. And how we wake up can not only affect our mood and day-to-day thinking, but also our cognition and mental performance.

In some cases, anger after waking up can be dangerous for hours later, by reducing our performance and determination (such as in a medical setting, emergency response, safety or while driving ala).

The mental state of reduced alertness is referred to as “sleep inertia”.

It is a growing concern because it can have serious consequences when you do strenuous activities, including driving.


The transition from sleep to wakefulness does not follow the on or off process, as shown by the brain imaging system.

Awakening depends on a complex biological process, including increased blood flow to the brain.

Studies show that the prefrontal cortical region takes longer to “start” than other areas (such as the basal ganglia) that are needed for stimulation.

This means you can be tetabut not quite at all.

Research has also shown blood flow activity in the brain is reduced to wake up, compared to the state before sleep.

Therefore, good vigilance may require systems that support blood circulation in the brain – something certain types of sounds and music can do.

HAT depends on the age

Another factor that affects staying awake when you wake up is sleep time at that time. You do not feel better if you wake up easier, compared to slow sleep or REM sleep.

Theta waves are measured (as measured by the electrical activity of the brain) and can be associated with sleep. During this sleep cycle, stimuli from outside stimuli such as screaming can quickly distract a person.

On the other hand, deep sleep or restless sleep includes frequent Delta, which is associated with unconsciousness. This is a more difficult sleeping level to wake up.

Effective alarm depending on age.

Young people between the ages of 18 and 25 need more screaming than older people, and teenagers need even more doors than young people.

You may need to sound up to 20 decibels louder at 18 than you would in 80.

Frequency and tone are important for screaming?

But when it comes to choosing an alarm, which is the best? A growing body of evidence suggests that different noise levels can affect a person’s performance after waking up.

Check out our series published in 2020 which shows frequency (sound level as compared to Hertz) about 500 Hz better in stimulating children than the 2000+ Hz range.

We have no research to say whether this also applies to adults, but it is thought that the same kind of cry would be helpful.

Voice messages like a “wake up!” works better than higher frequencies. However, they do not function as standard 500 Hz amplifiers – similar to those installed on most mobile phones.

Our research also examines how music, in particular music, plays a role in encouraging vigilance.

We found that the way people interpret their “sounds” also reflects how they feel after waking up.

Here, people, those who use their alarms to carry their fast-ready sounds will be more frustrated than those with the standard “ringing”.

With this in mind, we developed traditional music that brought performance to both sleep and wakefulness, compared to standard melodies.

We designed this experimental alarm to increase alertness and reduce morning sickness. (Stuart McFarlane)

Other studies have also found that popular music (which can be described as vocal chords) is good for preventing sleep apnea after a short period of time, and even more so if it is a music that the listener likes n ‘himself.


What does all this mean for day-to-day life? Well, given all of the above, we believe a complete scream would sound something like this:

  • it has aa music you can easily sing or hum along
  • it has a control frequency around 500 Hz, or the C5 key
  • It is not fast or fast (100 – 120 beats per minute is good).

Also, remember that crying is a must-have for teenagers (or for those who sleep a lot).

If we are considering the default alarm on our device, a lot of work is required – especially the test site in this new area. As a result, we anticipate that the availability of alarm downloads will increase over time.

Many sound insulation and sound effects will wake you up, but the models (like the one above) have been developed with the latest research that not only promotes motivation but also provides a great boost.
