Binaural frequencies are fascinating. Not only does listening to them allow you to fall asleep faster, but they also provide you with a deep sense of well-being.
HoomBand ne s’est donc pas privé de les ajouter, de différentes façons, à ses sons et histoires.
Because there are as many sleeper profiles as there are sleepers, the Livlab application (available on iPhone and Android) aims to be as comprehensive as possible, to provide a customizable solution, depending on each person's mood or sensitivity.
In this article, we try to understand how frequencies work and especially why they are so effective on sleep.
Summary:
- 1- What exactly is a binaural frequency?

1- What exactly is a binaural frequency?
These are sounds listened to with headphones and whose frequency differs from one ear to the other.
Your right ear perceives frequency n°1 and your left ear perceives frequency n°2 at the same time, but the sound content remains identical and "pleasant" to listen to.
Normally, the two hemispheres of the brain operate at different rhythms, but according to Foster's work in 1990, these sounds have the ability to synchronize these two hemispheres. With astonishing results...
2- Their effectiveness on the quality of your sleep
All brains emit waves, whose frequency can be measured in hertz.
There are 5 of them:
- Gamma waves (above 38 hertz): they are linked to a state of intense concentration, such as creativity and intellectual work.
- Beta waves (between 12 and 38 hertz): this is the alert state. Our brain emits them when our attention is focused on the outside world. These are the ones we emit the most.
- Alpha waves (between 8 and 12 hertz): this is a state of light relaxation.
- Theta waves (between 3 and 8 hertz): this is a state of deep relaxation or hypnosis.
- Delta waves (between 0.2 and 3 hertz): this is the state of very deep sleep
We are not used to "controlling" the emission of our brain waves (except for people who enter a very deep meditation state).
But by listening to binaural frequencies, this becomes possible!
When your right ear perceives a frequency of 400 hertz and your left ear perceives a frequency of 395 hertz, your brain will emit waves corresponding to the difference between the two frequencies, which is 5 hertz (which would correspond to emitting Theta waves and thus inducing a state of deep relaxation).
The smaller the difference, the deeper the relaxation.
A study published in 2019 specifies the scope of binaural frequencies by showing that they can increase positive emotions felt by listeners and sleep quality. [1]
3- Improve sleep, but not only...
Many studies have examined the effects of binaural frequencies on the human body.
And it goes far beyond sleep, since binaural frequencies would be particularly effective for:
- to increase alertness [2]
- to provide physical and mental relaxation [3]
- to regulate depressive states [4]
- to soothe anxiety in general [5]
Binaural frequencies deserve to be discovered and used by many people. The state of deep relaxation they induce would naturally help fight stress and improve sleep quality.
Let's summarize
Binaural frequencies and your HoomBand sont donc particulièrement efficaces :
- if you have trouble entering a state of deep relaxation
- if you want to improve your intellectual and creative abilities
- if you are going through a depressive episode or your thoughts are not very positive right now
Here is an example of a sound containing binaural frequencies available on the Livlab app (available on iPhone and Android) :
