Frequently Asked Questions (FAQ)
What Are Isochronic Tones?
Isochronic tones are the most effective form of brain wave stimulation using sound. In this process, rhythmic pulse tones of a certain frequency are played through headphones (e.g. 8Hz - 8 pulses per second), which leads to a coupling (entrainment) of the brain waves with the played frequency due to the frequency-following-response (FFR) of the brain. In this way, it is reliably possible to willingly induce various mental states, e.g. to relax, to conquer insomnia, to expand consciousness, to meditate, to energize etc. or also to improve and train mental abilities such as concentration, mindfulness, memory performance etc.
What Is Frequency-Following-Response (FFR)?
When brain waves couple and synchronize with the frequency of a given stimulation (e.g., isochronous tones), this is called the frequency-following response (FFR). If the frequency of the stimulation is modified, the brainwave frequency follows the modified stimulation due to the FFR.
What Does the Unit Hertz (Hz) Mean?
The unit Hertz was named after the German physicist Heinrich Rudolf Hertz and was introduced as a unit of measurement for frequency (both brain and sound waves). It indicates the number of oscillations/pulses per second, e.g. 8Hz for a frequency means that it oscillates or pulsates 8 times per second.
What Are Brain Waves?
Brain waves are generated by the electrical activity of our brain and can be read with an EEG device. The voltage fluctuations on the surface of the head are measured and recorded graphically. What you are thinking, feeling or doing at any given time directly affects which brain waves occur. Brain waves are divided into 5 ranges: DELTA (0.2Hz - 4Hz), THETA (4Hz - 8Hz), ALPHA (8Hz - 12Hz), BETA (12Hz - 38Hz) and GAMMA (from 38 Hz upwards).
What Are DELTA (0.2Hz - 4Hz) Brain Waves?
DELTA brain waves are the slowest brain waves and dominate during deep, dreamless sleep. Consciousness is inactive while the body regenerates, strengthens its immune system and releases healing hormones. Studies also show that stimulation with DELTA frequencies can reduce anxiety, relieve headaches and lead to improved sleep.
What Are THETA (4Hz - 8Hz) Brain Waves?
THETA brain waves occur during light sleep or deepest relaxation/meditation and characterize a state that turns its attention to the inner world. During this process, the subconscious mind is activated, allowing access to unconscious thoughts. As studies show, tuning with THETA frequencies increases the level of sensitivity to autosuggestions, creativity and imagination, as well as fantasy and learning ability. In addition, THETA frequencies are very effective in inducing hypnosis.
What Are ALPHA (8Hz - 12Hz) Brain Waves?
When ALPHA brainwaves dominate, it means that you are awake but calm and relaxed, and your attention is directed both inward and outward. Alpha brainwaves occur, for example, when we daydream or simply close our eyes in a relaxed state. In studies, stimulation with ALPHA waves has been shown to increase the clarity of visualizations, improve receptivity to suggestions, as well as significantly reduce stress.
What Are BETA (12Hz - 38Hz) Brain Waves?
BETA brainwaves are frequencies between 12Hz and 38Hz and dominate during the normal waking state that most people are in during the day. Attention is focused on the outside world or activities in the outside world. Studies show that stimulation with appropriate BETA waves can increase attention and concentration, improve sleep (SMR), have a positive impact on intelligence, and significantly reduce fatigue and motivational problems.
What Are GAMMA (38Hz +) Brain Waves?
GAMMA waves are frequencies above 38Hz and characterize states of highest concentration and activity which are extremely rare to reach by natural means.
