When is Pink Noise triggered?
Pink Noise is triggered during phases of consolidated deep sleep, when our algorithm detects a deep sleep phase of sufficient quality that lasts for at least 30 consecutive minutes. So a lot can depend on your initial sleep structure.
Why is Pink Noise disabled in the first week?
The aim of the first week is to objectively evaluate your sleep as it is, without any sleep aid, so that we can determine your Sleep Profile. During this period, Relaxation Techniques and Pink Noise are not yet unlocked.
Why is the amount of stimulations variable?
There are several reasons why you may receive more or less stimulation from one night to the next:
- Your sleep session includes too little deep sleep.
- Your sleep session includes deep sleep but our algorithm did not trigger any Pink Noise. This may be due to several events that disrupt your deep sleep and prevent your Dreem Band from sending the Pink Noise:
- Waking up during the night
- Fragmented deep sleep
- The signal quality of the Dreem Band is insufficient during periods of deep sleep. In this case the headband cannot determine the appropriate periods. It may become displaced or badly positioned during the night. For more info, head to our dedicated article How to: Position your Dreem Band.
The amount of Pink Noise can vary from one person to another, depending on each person's sleep characteristics.
What’s ‘stimulation impact’?
Stimulation impact is the increase in the amplitude of your slow waves through Pink Noise. It’s an impact on quality not on quantity of deep sleep.
Does volume have an impact on Pink Noise? Can I change it?
To be effective, the Pink Noise must be perceived but not wake you up. We have set up a system of individualized volume control that allows automatic and personalized adjustment of the volume according to your sensitivity. For this reason, it is not possible to set the volume yourself.
