Sleep Therapy

by Nordvargr



Sleep Therapy - an experiment with electroencephalography technology.

The dominant frequency in the brain's EEG pattern determines the current state of the brain. For example, If the amplitude of the Theta range frequencies is highest, then the brain is said to be in the Theta state. If external stimulus is applied to the brain, it becomes possible to entrain the brain frequency from one brain state to another (this phenomenon is called Frequency Following Response).

The purpose of the soundscapes of Sleep Therapy is to affect your brain's state to achieve a change of your sleeping behaviour, dreams and will - the result of this treatment is for you alone to experience.
The contents of these recordings are all ambient soundscapes to which EVP recordings and Theta / Delta frequencies have been added.
This is not entertainment.


released October 21, 2011

Directions of use

Use high quality stereo headphones and adjust the volume to a comfortable level. Try to fall asleep while listening to the sounds. If you get distracted, reduce the volume. The Theta / Delta waves are effective even at very low volume. Repeat the treatment for seven days.
If changes in your sleeping behaviour occurs, please report them to nordvargr@nordvargr.com.
